Theme Updates, Offline Upgrades Headline New Additions to Pop!_OS 19.10
Halloween came early this year with our latest release of Pop!_OS. Fill your treat bag with theme updates, Tensorman, easy upgrading, and more as we unwrap the details of Pop!_OS 19.10:
Theme Updates
A new Dark Mode for Pop!_OS is available in the operating system’s Appearance Settings. Both the Light and Dark modes feature higher contrast colors using a neutral color palette that’s easy on the eyes.
The functionality of Dark Mode has been expanded to include the shell, providing a more consistently dark aesthetic across your desktop. If you’re using the User Themes extension to set the shell theme, disable it to use the new integrated Light and Dark mode switcher.
The default theme on Pop!_OS has been rebuilt based on Adwaita. Though users may only notice a slight difference in their widgets, the new OS theme provides significant measures to prevent application themes from experiencing UI breakage. This breakage manifests in the application as missing or misaligned text, broken widgets, and scaling errors, and should not occur with the new theme in place.
The updated theme includes a new set of modernized sound effects. Users will now hear a sound effect when plugging and unplugging a USB or charging cable. The sound effect for adjusting the volume has been removed.
Tensorman
Tensorman is a new tool that we’ve developed to serve as a toolchain manager for Tensorflow, using the official Docker builds of Tensorflow. For example, executing a python script inside of a Tensorflow Docker container with CUDA GPU and Python 3 support will now be as simple as running:
tensorman run --gpu python -- ./script.py
Tensorman allows users to define a default version of Tensorflow user-wide, project-wide, and per run. This will enable all releases of Pop!_OS to gain equal support for all versions of Tensorflow, including pre-releases, without needing to install Tensorflow or the CUDA SDK in the system. Likewise, new releases of Tensorflow upstream will be made immediately available to install with Tensorman.
Examples of how to use Tensorman are in the tool’s support page. Tensorman is now available on Pop!_OS 19.10, and will be coming to Pop!_OS 18.04 LTS soon.
To install Tensorman, enter this command into the Terminal:
sudo apt install tensorman
GNOME 3.34
In addition to theming improvements, the GNOME 3.34 release brings some new updates to the fold. From GNOME’s 3.34 Release Notes:
A redesigned Background panel landed in the Appearance settings. Now when you select a background, you will see a preview of it under the desktop panel and lock screen. Custom backgrounds can now be added via the Add Picture… button.
Performance improvements bring smoother animations and a more responsive desktop experience.
Icons in the application overview can be grouped together into folders. To do this, drag an icon on top of another to create a group. Removing all icons from a group will automatically remove the group, too. This makes organizing applications much easier and keeps the application overview clutter-free.
The visual style for the Activities overview was refined as well, including the search entry field, the login password field, and the border that highlights windows. All these changes give the GNOME desktop an improved overall experience.
Some animations in the Activities overview have been refactored, resulting in faster icon loading and caching.
The Terminal application now supports right-to-left and bi-directional languages.
The Files application now warns users when attempting to paste a file into a read-only folder.
Search settings for the Activities overview can now be reordered in the Settings application by dragging them in the settings list. The Night Light section has been moved to the Display panel.
New Upgrade Process
Offline upgrades are now live on Pop!_OS 19.04, bringing faster, more reliable upgrades. When an upgrade becomes available, it is downloaded to your computer. Then, when you decide to upgrade to the newest version of your OS, the upgrade will overwrite the current version of your software. However, this is not to be confused with an automatic update; your OS will remain on the current version until you yourself decide to upgrade.
To upgrade to 19.10 from a fully updated version of Pop!_OS 19.04, open the Settings application and scroll down on the sidebar menu to the Details tab. In the About panel of the Details tab, you will see a button to download the upgrade. Once the download is complete, hit the button again to upgrade your OS. This will be the standard method of upgrading between Pop!_OS releases going forward.
Alternatively, a notification will appear when your system is ready to upgrade. This notification appears on your next login on your fully updated version of Pop!_OS 19.10. Clicking it will take you to the About panel in the Settings application.
In early November, Pop!_OS 18.04 LTS users will be notified to update to Pop!_OS 19.10 or remain on 18.04 until the next LTS version is available.
New to Pop!_OS:
Visit the official Pop!_OS page to download Pop!_OS 19.10.
Upgrade Ubuntu to 19.10
See our support article on upgrading Ubuntu for information on how to upgrade Ubuntu 19.04 to 19.10.

Parity Wallet
The Parity Wallet is one of several well-liked remedies that were designed for you to serve as each a wallet and a software between the Ethereum software and your laptop or computer. Like MyEtherWallet, Parity is genuinely a browser and not some sort of budget. Parity even bills itself as an �Ethereum Browser� � a web browser is needed because Ethereum is really an extensive system. The idea guiding Parity is to provide the particular most effective connection between Ethereum and various technologies possible. Ethereum came to be as a decentralized data safe-keeping solution, but it is widespread since cryptocurrency because it will be encrypted and very safe. The great way to think of Ethereum is a new second, encrypted network in the internet. Parity is created like a entrance to that network together with an software between the web and even Ethereum. A FULL NODE WALLET Parity was designed since a full-node pocket book the fact that means you can carry out everything this. You will store Ethereum and ERC-20 up to date initial cryptocurrency solutions (ICOs). More importantly, you are able to send and receive bills, buy and sell Azure and ICO tokens, mine, invest in Ethereum plus add the wallet with a wide variety of programs. That makes Parity Ethereum management tool you can add to a number regarding internet browsers and run upon a number of operating systems. Presently, it works with Ubuntu, OS 10, Dockers and Home windows. One reason why users like the Parity Wallet is definitely that provides a dashboard that can be used to manage Ether on your own screen. It will perhaps purpose on desktops just where MyEtherWallet and Mist have got been extra. EASY TO BE ABLE TO USE Parity is pretty effortless if you abide by the instructions in the dash, which are fairly straightforward together with explanatory. If anyone look carefully you ought to see everything explained in order to anyone. This makes saving and managing Ethereum since easy as shopping with Amazon. Although it might take a good while to get your money to exhibit way up in Parity, users survey that it takes many time to be able to record dealings. Another favorite feature is the easy recovery bed sheet with a quick study (QR) code that an individual can scan with nearly any phone. That permits you regain your Parity account quick if that is lost or your own personal pc crashes. LOTS INVOLVING SUPPORT Several developers and even consumers like Parity mainly because the idea has a lot of assist. It is quite uncomplicated to contact and assist the firm responsible intended for the finances. The browser was the creation of the company named Parity Solutions. Based in Manchester and Munich, Parity�s aim is certainly to create a superfast networking that combines expert to see payments, networking, algorithms, cryptography, databases, and decentralized purposes. This provides a new more specialized operation in addition to a higher level connected with assistance than some connected with Parity�s challengers. Parity offers what it wants to phone the �world�s best plus lightest client� that may be included immediately into a net cell phone browser. That means it is a lot a great deal more than a wallet. You can store, receive and send Ethereum by means of Parity, yet you can likewise create or execute contracts and even design, deploy, plus any wide variety involving Ethereum-based applications. The best way it does that is to be able to work as the interface involving various networks. The assist on Parity includes device tests and review designed to make certain every performs. That also contains some associated with the most experienced cryptocurrency technical engineers around. HIGH AMOUNT OF KNOWLEDGE Parity Systems includes some of the people that helped develop Ethereum itself. Parity�s founder Doctor Gavin Solid wood, worked well together with Ethereum founder Vitalik Buterin when this individual first designed the blockchain system. Wood is actually wanting to develop a greater and much more comprehensive Ethereum software built to serve as the full-service payment network. Often the Parity Wallet is meant to become the cornerstone of that system. Ethereum Parity v2.3.4 can be to create next-generation Fin-Tech solutions which can be marketed for you to banks, retailers, off-set money, credit card companies, governing bodies, and other organizations. These remedies would certainly utilize the Ethereum blockchain to make market segments, retail systems, and economic products. THE FEATURES CONNECTED WITH PARITY Some Parity�s illustrates and selling things incorporate: Will work with The apple company McIntosh computers via the OSX operating technique. Will certainly work using the Linux-based Ubuntu operating system. Works together with an ecommerce applications software called Docker. Basic one-word online setup intended for Apple pc and Ubuntu, and perhaps Stainless and Android. PARITY FEATURES The most impressive matter about Parity is several of the very advanced features it provides. They look to possibly be years prior to other wallets and handbags and might supply a good more effective payment alternative. Competitors would be well-advised to help imitate some of Parity�s very-impressive new attributes. These are a little technological but if they will work as offered, those people features will make Parity of the best level of privacy wallets currently available. One least appreciated Parity attribute is often the Rust programming terminology which usually is low-level. That helps make Parity, simple and faster than other wallets and handbags, and even should reduce errors. Rust will allow the creation regarding complex smart contracts using JITEVM turbocharging and multi-level storage caching. Parity Systems claims that Rust guarantees safety with actor-based modality, unit testing, and expert review. That is made to create a better made and resilient process. More levels of durability are really created along with a standard, JSON-based company specs structure, native rate contracts plus modular design. Higher levels of security, privateness, and even anonymity are offered by means of Parity�s small impact. Acquiring a small footprint helps make Parity harder to detect and track on-line. A smaller footprint provides a bigger level involving cache management and generates a more compact storage footprint that is certainly less complicated to manage but harder for the bad guys to be able to discover. Even though the website fails to mention Android mobile phone or Chromium, the builders claim it truly is highly suitable with Linux-based operating systems. This kind of is achieved through 100% test conformant consensus conformant execution, standard devp2p community standard protocol, and full match ups with JSON-RPC-API. All the fact that should really make Parity specific simple to operate with one collection Apple pc and even Linux installation. That means one line installation on Chrome and even Android might be available for the reason that those Google solutions usually are Linux-based. Installation can furthermore be made with Docker photos. PARITY VS MYETHERWALLET Parity by far is made for the considerably more techie user who needs to get smart having the interior workings associated with ethereum wallets and handbags. There� Parity Wallet Download 2.4.0 for stuff like multisig legal papers, manual adjustment associated with GWEI (useful if a person are trying to find directly into a new highly reasonably competitive ICO) values, and more. However, Parity does not necessarily have the easiest-to-use user interface and, as things proceed, certainly not as user-friendly as MyEtherWallet. Power users will certainly almost certainly prefer Parity in excess of MyEther Wallet. Casual consumers who else just need a good private pocket to shop ERC20 tokens will most likely desire MyEtherWallet Is Parity with regard to You? All this creates Parity a great solution for severe Ethereum geeks and people that are trying to developing next-generation Ethereum solutions. Parity would end up being a great use for you if you want for you to create or maybe execute great contracts one example is. Persons together with organizations that want a internet browser that can help average people access and usage Ethereum would be well-served simply by Parity. That causes a great substitute for ecommerce companies and fiscal professionals. Parity may well certainly not be a good alternate for somebody who is definitely just searching for a good suggests of buying, stocking, sending and trading Ethereum. The big drawback to Parity that individuals can see is definitely that this will not look to be compatible together with any of the well-liked cryptocurrency hardware wallets. It appears to be as if no assist can be obtained for the TREZOR or any in the Journal products such as this Piccolo S. That may well make MyEtherWallet which will easily be installed on often the TREZOR and Piccolo T, some sort of better alternative. Why You Need More in comparison with Only one Cryptocurrency Wallet A good totally obvious solution for the particular person that will wants for you to store Ethereum will be to possess two or more wallets and handbags. A major advantage to Parity is that it is supposed to be compatible with pouches like the Mist together with MyEtherWallet. A person can use Parity regarding sophisticated Ethereum tasks like making money with smart contracts, as well as the additional wallet for storing altcoins or switching it to equipment wallets. One of typically the best strengths to Parity is that it is creators� acknowledge the need for several wallet. If an individual watch good news, you almost certainly know that every altcoin within the sun has been recently hacked. Using two or maybe more wallets can add more security and produce the idea harder for crooks to swipe your current coins. Parity�s recognition on this a weakness in addition to the need for diversity is a solid marketing point with regard to the items. It might likewise possibly be an indication that Parity Technologies is planning some other products in the future such as a Australian visa or MasterCard debit credit card or a mobile app that converts cryptocurrency for you to fiat currencies such while money. A smart strategy is to possess two or more wallets and handbags with your computer and much more in comparison with one hardware wallet. A good good mix of billfolds would have been a Parity, MyEtherWallet, a new standard commercial wallet like Coinbase, a trading remedy like CEX. IO, a TREZOR for travel, one other components wallet for storage space, including least wallet using a MasterCard or Australian visa payment selection. There may be now several wallets linked to MasterCard and Visa debit cards such as TenX. These a option would be some sort of superior option � as you can make use of the debit card in places like the grocery store and also to get dollars from ATMs if have be. A VERY INNOVATIVE BUDGET WITH A LARGE LEVEL OF TESTING You should definitely consider using Parity should you need an innovative wallet that provides a great deal of support. The Parity Technological innovation Team seems to offer a lot more support and a new a higher level00 seriousness than a few of it is competitors. Their best attribute is undertaking a lot of examining. There is certainly enough support to help create a merchandise honestly, that is stable and basically gets results. Unlike some other altcoin solution providers, Parity Technology tests its merchandise alone rather than dumping all of them out online for uninformed consumers to tests. A proven way Parity tries to sustain sturdiness and stability is definitely by trying to test and release new editions or updates every six weeks. An additional is through 100 % unit-testing which many cryptocurrency geeks know is definately not often the industry standard. Parity features even managed to conduct more than 1, 000 opinion checks in a great hard work to be sure its products really work. Individuals reviews contain static program code checking, and even obtaining more than one expert programmers review every single update in advance of it is revealed. In the event you need a wallet of which completely has to help work, Parity is intended for you. The testing should really provide a higher levels of resilience plus trustworthiness than you are possibly utilized to. HIGH LEVEL REGARDING TRANSPARENCY Additionally, Parity basically outlines its� testing techniques and procedures online. This actually goes out of the way to reveal this kind of attributes as block-processing rate, memory footprint, and trie benchmarks online. That indicates techies can actually for you to see if Parity�s promises are for real. Parity Wallet v2.3.4 delivers a far higher amount of transparency than will be usually seen through several crypto solution suppliers. It is a true start taken solution created using a dangerous of visibility and sincerity. Developers will certainly definitely appreciate the fact that although so will regular people that want something sufficient for the pros to be able to use. A person big advantages to Parity is the fact that the idea is a professional alternative.
PARITY IS A GOOD SOLUTION FOR ENTREPRENEURS When you need something of which developers might access in addition to play with, Parity is normally definitely for you. That would help it become some sort of fine solution for anyone that is trying to produce smart contracts, a good ICO, or an Ethereum-based web commerce market platform, or product. Somebody that expects to hire a team connected with engineers to help develop a good new Ethereum-solution would be incredibly well served by Parity. So would entrepreneurs looking to do business with large institutions such like big banks, governments, large firms, investment banking institutions, hedge funds, credit-card providers, and technology companies.

That makes Parity a great choice of finances for those trying for you to create or even design following generation internet solutions. In case you own a organization or website and you want to add more Ethereum � Parity will be a great way to do the idea. This means Parity is certainly not necessarily a fantastic solution to get private individuals. It appears to be like some sort of business solution for professionals � that requires some level of technical skills to implement. In case you want to understand Ethereum and how to help produce Ethereum-based solutions, you should definitely get informed about Parity and learn to use it. Persons that will just want to make use of Ethereum as a repayment alternative, might be better served by way of a more consumer-friendly solution like MyEtherWallet. With luck ,, the Parity Technologies group will generate a simpler version of their wallet for use by this general public eventually. Their product is impressive and it also deserves to find the large advertise and market. Note that typically the split developers behind parity are putting their abilities in to developing a new crypto that aims to become the next big movement above ethereum � many might argue the next generation regarding blockchain technological innovation � using a internet of �blockchains� that aims to interface together with connect with different blockchains. This new cryptocurrency is termed Polkadot and goes survive Q4 2019. People the fact that want to see what a cryptocurrency wallet plus an Ethereum browser have to look such as must check out Parity. Parity Ethereum v2.3.5 might well come to be the yellow metal standard involving Ethereum-interface alternatives.

Are you a web developer with a need for fast, secure, and limitless data storage?
Ever heard of WordPress, Joomla, or Drupal? Well, they are all database-driven web applications that use MySQL. If you’re aiming high for your website, then MySQL has the performance power to help you succeed.
It’s easier than you think to download and benefit from MySQL for Mac. If you’re ready to get started on advancing your database management system, then read on to learn how!
What is MySQL?
MySQL is considered the world’s most popular open source relational database management system. It is a way for you to manage the data stored on your computer.
Your Mac computer can already hold a lot of data. MySQL will help you manage it and can collaborate with a number of application programming interfaces (APIs). It is known for being the go-to database management system for popular websites such as Facebook, Google, Twitter, and Uber.
MySQL uses Structured Query Language (SQL), which the most common standardized language used to access databases.
If you are working on software or websites that require MySQL database, then you should probably download it to your computer!
Let’s get started!
Anyone Can Download MySQL for Mac
One benefit to using MySQL is it is an open source software. That means anyone can download it and modify the code as needed. The software is licensed under the GNU General Public License (GPL).
The nice thing about this is developers around the world are able to update the software and are continuously fixing bugs in it.
If you’re looking to embed MySQL software into commercial applications, then you can purchase a commercial license. This will prevent you from having to share source code or be subject to the GPL license.
MySQL for Mac is Fast
Using the MySQL server is easy on your Mac laptop or desktop. Plus it is reliable in its speed and security. This makes it ideal for accessing databases on the Internet.
It won’t slow down when running along with your other applications and web servers. In fact, you can adjust the settings to use the full memory, CPU power, and I/O capabilities. Some developers will dedicate an entire computer to MySQL for this exact purpose.
In other cases, you can use MySQL to work with multiple machines connected together through a network. It can handle all types of large projects!

Download MySQL for Free
Many web servers and websites are going to include a MySQL download as a service they provide. Mac OS X doesn’t ship with a copy of MySQL included, but it’s free to download. You can download it on your own.
Simply go to MySQL’s website and download the standard Mac OS installer package. Make sure you click on the latest version and you select the DMG archive version. This will include the server as well as command line utilities.
Steps to Download MySQL for Mac
After you click the Download button, you will be prompted to sign up for an Oracle Web Account. This is optional so you can skip it if you want.
The MySQL for mac download weighs about 70MB.
Next, go to your Downloads file and double-click on the DMG archive. You will then double-click on the .pkg file. Step by step instructions will be provided in the setup wizard.
You will need to read and agree to the license terms. Then continue until you reach the Install button.
Don’t Forget the Password!
Before you close down the setup wizard, make sure you write down the temporary password given. Don’t lose this! It cannot be recovered. Once you log in to MySQL using the temporary password, it will prompt you to create your own.
Double-click the MySQL.prefPane file to download the MySQL control panel. This will install your control panel into the System Preferences application.
Ready to open MySQL? Just go to System Preferences on your computer. There you will click on the Other section. You should see the MySQL icon. Click on Start MySQL and you’re ready to go!
Open MySQL
To open MySQL you will need to go to the MySQL Preference Pane, which was part of the installation. Click on Start. It’s that easy!
You can also configure MySQL to start automatically when you turn on your computer. Just use the MySQL Preference Pane to change your settings.
Is Your MySQL Running?
Here’s an easy way to check and make sure MySQL is running properly on your computer. Open the Activity Viewer by going to Applications and then Utilities. Click on All Processes in the popup menu. In the search bar, type in the phrase mysqld.
You should see a mysqld process showing that MySQL is running!
Get MySQL Workbench
Download Mysql Server For Mac
You’re going to need to download MySQL Workbench as a visual tool to allow you to create a server instance. The MySQL Workbench will help you in the design and development process to create ER models, forward and reverse engineering, as well as SQL queries.
It creates an easy to view and organize dashboard to help you manage users, query database health, and audit your MySQL environment with ease.
Once you download MySQL Workbench go to the Server Administration section and click on New Server Instance to get started. You’re going to need some developer knowledge to work in this tool.
Web Development Packages
You may be interested in using web development packages for your mac that are compatible with MySQL. MAMP/XAMPP give you the ability to create PHP pages using Apache and MySQL.
Mysql Server Client For Mac
These packages include Apache and MySQL within them. Which makes them another way to download MySQL to your Mac along with some other various utilities.

Start Docker In Ubuntu

A Linux Dev Environment on Windows with WSL 2, Docker Desktop And the docker docs. Docker Desktop WSL 2 backend. Below is valid only for WSL1. It seems that docker cannot run inside WSL. What they propose is to connect the WSL to your docker desktop running in windows: Setting Up Docker for Windows and WSL. By removing /etc/docker you will loose all Images and data. You can check logs with. Journalctl -u docker.services. Systemctl daemon-reload && systemctl enable docker && systemctl start docker. This worked for me.
$ docker images REPOSITORY TAG ID ubuntu 12.10 b750fe78269d me/myapp latest 7b2431a8d968. Docker-compose start docker-compose stop. After installing the Nvidia Container Toolkit, you'll need to restart the Docker Daemon in order to let Docker use your Nvidia GPU: sudo systemctl restart docker Changing the docker-compose.yml Now that all the packages are in order, let's change the docker-compose.yml to let the Jellyfin container make use of the Nvidia GPU.

Container images
Official container image: jellyfin/jellyfin.
LinuxServer.io image: linuxserver/jellyfin.
hotio image: hotio/jellyfin.
Jellyfin distributes official container images on Docker Hub for multiple architectures. These images are based on Debian and built directly from the Jellyfin source code.
Additionally the LinuxServer.io project and hotio distribute images based on Ubuntu and the official Jellyfin Ubuntu binary packages, see here and here to see their Dockerfile.
Note
For ARM hardware and RPi, it is recommended to use the LinuxServer.io or hotio image since hardware acceleration support is not yet available on the native image.
Docker
Docker allows you to run containers on Linux, Windows and MacOS.
The basic steps to create and run a Jellyfin container using Docker are as follows.
Follow the offical installation guide to install Docker.
Download the latest container image.
Create persistent storage for configuration and cache data.
Either create two persistent volumes:
Or create two directories on the host and use bind mounts:
Create and run a container in one of the following ways.
Note
The default network mode for Docker is bridge mode. Bridge mode will be used if host mode is omitted. Use host mode for networking in order to use DLNA or an HDHomeRun.
Using Docker command line interface:
Using host networking (--net=host) is optional but required in order to use DLNA or HDHomeRun.
Bind Mounts are needed to pass folders from the host OS to the container OS whereas volumes are maintained by Docker and can be considered easier to backup and control by external programs. For a simple setup, it's considered easier to use Bind Mounts instead of volumes. Replace jellyfin-config and jellyfin-cache with /path/to/config and /path/to/cache respectively if using bind mounts. Multiple media libraries can be bind mounted if needed:
Note
There is currently an issue with read-only mounts in Docker. If there are submounts within the main mount, the submounts are read-write capable.
Using Docker Compose:
Create a docker-compose.yml file with the following contents:
Then while in the same folder as the docker-compose.yml run:
To run the container in background add -d to the above command.
You can learn more about using Docker by reading the official Docker documentation.
Hardware Transcoding with Nvidia (Ubuntu)
You are able to use hardware encoding with Nvidia, but it requires some additional configuration. These steps require basic knowledge of Ubuntu but nothing too special.
Adding Package RepositoriesFirst off you'll need to add the Nvidia package repositories to your Ubuntu installation. This can be done by running the following commands:
Installing Nvidia container toolkitNext we'll need to install the Nvidia container toolkit. This can be done by running the following commands:
After installing the Nvidia Container Toolkit, you'll need to restart the Docker Daemon in order to let Docker use your Nvidia GPU:
Changing the docker-compose.ymlNow that all the packages are in order, let's change the docker-compose.yml to let the Jellyfin container make use of the Nvidia GPU.The following lines need to be added to the file:
Your completed docker-compose.yml file should look something like this:
Note
For Nvidia Hardware encoding the minimum version of docker-compose needs to be 2. However we recommend sticking with version 2.3 as it has proven to work with nvenc encoding.
Unraid Docker
An Unraid Docker template is available in the repository.
Open the unRaid GUI (at least unRaid 6.5) and click on the 'Docker' tab.

Kubernetes
A community project to deploy Jellyfin on Kubernetes-based platforms exists at their repository. Any issues or feature requests related to deployment on Kubernetes-based platforms should be filed there.
Podman
Podman allows you to run containers as non-root. It's also the offically supported container solution on RHEL and CentOS.
Steps to run Jellyfin using Podman are almost identical to Docker steps:
Install Podman:
Download the latest container image:
Create persistent storage for configuration and cache data:
Either create two persistent volumes:
Or create two directories on the host and use bind mounts:
Create and run a Jellyfin container:
Note that Podman doesn't require root access and it's recommended to run the Jellyfin container as a separate non-root user for security.
If SELinux is enabled you need to use either --privileged or supply z volume option to allow Jellyfin to access the volumes.
Replace jellyfin-config and jellyfin-cache with /path/to/config and /path/to/cache respectively if using bind mounts.
To mount your media library read-only append ':ro' to the media volume:

To run as a systemd service see Running containers with Podman and shareable systemd services.
Cloudron
Cloudron is a complete solution for running apps on your server and keeping them up-to-date and secure. On your Cloudron you can install Jellyfin with a few clicks via the app library and updates are delivered automatically.
The source code for the package can be found here.Any issues or feature requests related to deployment on Cloudron should be filed there.
Windows (x86/x64)
Windows installers and builds in ZIP archive format are available here.
Warning
If you installed a version prior to 10.4.0 using a PowerShell script, you will need to manually remove the service using the command nssm remove Jellyfin and uninstall the server by remove all the files manually. Also one might need to move the data files to the correct location, or point the installer at the old location.

More detailed download options, documentation, and signatures can be found.
If using static build, extract it to the /Applications/ folder.
Navigate to the Playback tab in the Dashboard and set the path to FFmpeg under FFmpeg Path.
Linux
Linux (generic amd64)
Generic amd64 Linux builds in TAR archive format are available here.
Installation Process
Create a directory in /opt for jellyfin and its files, and enter that directory.
Download the latest generic Linux build from the release page. The generic Linux build ends with 'linux-amd64.tar.gz'. The rest of these instructions assume version 10.4.3 is being installed (i.e. jellyfin_10.4.3_linux-amd64.tar.gz). Download the generic build, then extract the archive:
Create a symbolic link to the Jellyfin 10.4.3 directory. This allows an upgrade by repeating the above steps and enabling it by simply re-creating the symbolic link to the new version.
Create four sub-directories for Jellyfin data.
If you are running Debian or a derivative, you can also download and install an ffmpeg release built specifically for Jellyfin. Be sure to download the latest release that matches your OS (4.2.1-5 for Debian Stretch assumed below).
If you run into any dependency errors, run this and it will install them and jellyfin-ffmpeg.
Due to the number of command line options that must be passed, it is easiest to create a small script to run Jellyfin.
Then paste the following commands and modify as needed.
Assuming you desire Jellyfin to run as a non-root user, chmod all files and directories to your normal login user and group. Also make the startup script above executable.
Finally you can run it. You will see lots of log information when run, this is normal. Setup is as usual in the web browser.
Portable DLL
Platform-agnostic .NET Core DLL builds in TAR archive format are available here. These builds use the binary jellyfin.dll and must be loaded with dotnet.
Arch Linux
Jellyfin can be found in the AUR as jellyfin, jellyfin-bin and jellyfin-git.
Fedora
Fedora builds in RPM package format are available here for now but an official Fedora repository is coming soon.
You will need to enable rpmfusion as ffmpeg is a dependency of the jellyfin server package
Note
You do not need to manually install ffmpeg, it will be installed by the jellyfin server package as a dependency
Install the jellyfin server
Install the jellyfin web interface
Enable jellyfin service with systemd
Open jellyfin service with firewalld
Note
This will open the following ports8096 TCP used by default for HTTP traffic, you can change this in the dashboard8920 TCP used by default for HTTPS traffic, you can change this in the dashboard1900 UDP used for service auto-discovery, this is not configurable7359 UDP used for auto-discovery, this is not configurable
Reboot your box
Go to localhost:8096 or ip-address-of-jellyfin-server:8096 to finish setup in the web UI
CentOS
CentOS/RHEL 7 builds in RPM package format are available here and an official CentOS/RHEL repository is planned for the future.
The default CentOS/RHEL repositories don't carry FFmpeg, which the RPM requires. You will need to add a third-party repository which carries FFmpeg, such as RPM Fusion's Free repository.
You can also build Jellyfin's version on your own. This includes gathering the dependencies and compiling and installing them. Instructions can be found at the FFmpeg wiki.

Elasticsearch will then only be accessible from the host machine itself. The Docker named volumes data01, data02, and data03 store the node data directories so the data persists across restarts. If they don’t already exist, docker-compose creates them when you bring up the cluster. Make sure Docker Engine is allotted at least 4GiB of memory. Docker Engine 1.12 introduced a new swarm mode for natively managing a cluster of Docker Engines called a swarm. Docker swarm mode implements Raft Consensus Algorithm and does not require using external key value store anymore, such as Consul or etcd. If you want to run a swarm cluster on a developer’s machine, there are several options.
« Install Elasticsearch with Windows MSI InstallerInstall Elasticsearch on macOS with Homebrew »
Elasticsearch is also available as Docker images.The images use centos:8 as the base image.
A list of all published Docker images and tags is available atwww.docker.elastic.co. The source filesare inGithub.
This package contains both free and subscription features.Start a 30-day trial to try out all of the features.
Obtaining Elasticsearch for Docker is as simple as issuing a docker pull commandagainst the Elastic Docker registry.
To start a single-node Elasticsearch cluster for development or testing, specifysingle-node discovery to bypass the bootstrap checks:
Starting a multi-node cluster with Docker Composeedit
To get a three-node Elasticsearch cluster up and running in Docker,you can use Docker Compose:
This sample docker-compose.yml file uses the ES_JAVA_OPTSenvironment variable to manually set the heap size to 512MB. We do not recommendusing ES_JAVA_OPTS in production. See Manually set the heap size.
This sample Docker Compose file brings up a three-node Elasticsearch cluster.Node es01 listens on localhost:9200 and es02 and es03 talk to es01 over a Docker network.
Please note that this configuration exposes port 9200 on all network interfaces, and given howDocker manipulates iptables on Linux, this means that your Elasticsearch cluster is publically accessible,potentially ignoring any firewall settings. If you don’t want to expose port 9200 and instead usea reverse proxy, replace 9200:9200 with 127.0.0.1:9200:9200 in the docker-compose.yml file.Elasticsearch will then only be accessible from the host machine itself.
The Docker named volumesdata01, data02, and data03 store the node data directories so the data persists across restarts.If they don’t already exist, docker-compose creates them when you bring up the cluster.
Make sure Docker Engine is allotted at least 4GiB of memory.In Docker Desktop, you configure resource usage on the Advanced tab in Preference (macOS)or Settings (Windows).
Docker Compose is not pre-installed with Docker on Linux.See docs.docker.com for installation instructions:Install Compose on Linux
Run docker-compose to bring up the cluster:
Submit a _cat/nodes request to see that the nodes are up and running:
Log messages go to the console and are handled by the configured Docker logging driver.By default you can access logs with docker logs. If you would prefer the Elasticsearchcontainer to write logs to disk, set the ES_LOG_STYLE environment variable to file.This causes Elasticsearch to use the same logging configuration as other Elasticsearch distribution formats.

To stop the cluster, run docker-compose down.The data in the Docker volumes is preserved and loadedwhen you restart the cluster with docker-compose up.To delete the data volumes when you bring down the cluster,specify the -v option: docker-compose down -v.
See Encrypting communications in an Elasticsearch Docker Container andRun the Elastic Stack in Docker with TLS enabled.
The following requirements and recommendations apply when running Elasticsearch in Docker in production.
The vm.max_map_count kernel setting must be set to at least 262144 for production use.
How you set vm.max_map_count depends on your platform:
Linux
The vm.max_map_count setting should be set permanently in /etc/sysctl.conf:
To apply the setting on a live system, run:
macOS with Docker for Mac
The vm.max_map_count setting must be set within the xhyve virtual machine:
From the command line, run:
Press enter and use`sysctl` to configure vm.max_map_count:
To exit the screen session, type Ctrl a d.
Windows and macOS with Docker Desktop
The vm.max_map_count setting must be set via docker-machine:
Windows with Docker Desktop WSL 2 backend
The vm.max_map_count setting must be set in the docker-desktop container:
Configuration files must be readable by the elasticsearch useredit
By default, Elasticsearch runs inside the container as user elasticsearch usinguid:gid 1000:0.
One exception is Openshift,which runs containers using an arbitrarily assigned user ID.Openshift presents persistent volumes with the gid set to 0, which works without any adjustments.
If you are bind-mounting a local directory or file, it must be readable by the elasticsearch user.In addition, this user must have write access to the config, data and log dirs(Elasticsearch needs write access to the config directory so that it can generate a keystore).A good strategy is to grant group access to gid 0 for the local directory.
For example, to prepare a local directory for storing data through a bind-mount:
You can also run an Elasticsearch container using both a custom UID and GID. Unless youbind-mount each of the config, data` and logs directories, you must passthe command line option --group-add 0 to docker run. This ensures that the userunder which Elasticsearch is running is also a member of the root (GID 0) group inside thecontainer.
As a last resort, you can force the container to mutate the ownership ofany bind-mounts used for the data and log dirs through theenvironment variable TAKE_FILE_OWNERSHIP. When you do this, they will be owned byuid:gid 1000:0, which provides the required read/write access to the Elasticsearch process.
Increased ulimits for nofile and nprocmust be available for the Elasticsearch containers.Verify the init systemfor the Docker daemon sets them to acceptable values.
To check the Docker daemon defaults for ulimits, run:
If needed, adjust them in the Daemon or override them per container.For example, when using docker run, set:
Swapping needs to be disabled for performance and node stability.For information about ways to do this, see Disable swapping.
If you opt for the bootstrap.memory_lock: true approach,you also need to define the memlock: true ulimit in theDocker Daemon,or explicitly set for the container as shown in the sample compose file.When using docker run, you can specify:
The image exposesTCP ports 9200 and 9300. For production clusters, randomizing thepublished ports with --publish-all is recommended,unless you are pinning one container per host.
By default, Elasticsearch automatically sizes JVM heap based on a nodes’sroles and the total memory available to the node’s container. Werecommend this default sizing for most production environments. If needed, youcan override default sizing by manually setting JVM heap size.
To manually set the heap size in production, bind mount a JVMoptions file under /usr/share/elasticsearch/config/jvm.options.d thatincludes your desired heap size settings.

For testing, you can also manually set the heap size using the ES_JAVA_OPTSenvironment variable. For example, to use 16GB, specify -eES_JAVA_OPTS='-Xms16g -Xmx16g' with docker run. The ES_JAVA_OPTS variableoverrides all other JVM options. The ES_JAVA_OPTS variable overrides all otherJVM options. We do not recommend using ES_JAVA_OPTS in production. Thedocker-compose.yml file above sets the heap size to 512MB.
Pin your deployments to a specific version of the Elasticsearch Docker image. Forexample docker.elastic.co/elasticsearch/elasticsearch:7.12.0.
You should use a volume bound on /usr/share/elasticsearch/data for the following reasons:
The data of your Elasticsearch node won’t be lost if the container is killed
Elasticsearch is I/O sensitive and the Docker storage driver is not ideal for fast I/O
It allows the use of advancedDocker volume plugins
If you are using the devicemapper storage driver, do not use the default loop-lvm mode.Configure docker-engine to usedirect-lvm.
Consider centralizing your logs by using a differentlogging driver. Alsonote that the default json-file logging driver is not ideally suited forproduction use.
When you run in Docker, the Elasticsearch configuration files are loaded from/usr/share/elasticsearch/config/.
To use custom configuration files, you bind-mount the filesover the configuration files in the image.
You can set individual Elasticsearch configuration parameters using Docker environment variables.The sample compose file and thesingle-node example use this method.
To use the contents of a file to set an environment variable, suffix the environmentvariable name with _FILE. This is useful for passing secrets such as passwords to Elasticsearchwithout specifying them directly.
For example, to set the Elasticsearch bootstrap password from a file, you can bind mount thefile and set the ELASTIC_PASSWORD_FILE environment variable to the mount location.If you mount the password file to /run/secrets/bootstrapPassword.txt, specify:
You can also override the default command for the image to pass Elasticsearch configurationparameters as command line options. For example:
While bind-mounting your configuration files is usually the preferred method in production,you can also create a custom Docker imagethat contains your configuration.
Create custom config files and bind-mount them over the corresponding files in the Docker image.For example, to bind-mount custom_elasticsearch.yml with docker run, specify:
The container runs Elasticsearch as user elasticsearch usinguid:gid 1000:0. Bind mounted host directories and files must be accessible by this user,and the data and log directories must be writable by this user.
By default, Elasticsearch will auto-generate a keystore file for secure settings. Thisfile is obfuscated but not encrypted. If you want to encrypt yoursecure settings with a password, you must use theelasticsearch-keystore utility to create a password-protected keystore andbind-mount it to the container as/usr/share/elasticsearch/config/elasticsearch.keystore. In order to providethe Docker container with the password at startup, set the Docker environmentvalue KEYSTORE_PASSWORD to the value of your password. For example, a dockerrun command might have the following options:
In some environments, it might make more sense to prepare a custom image that containsyour configuration. A Dockerfile to achieve this might be as simple as:
You could then build and run the image with:
Some plugins require additional security permissions.You must explicitly accept them either by:
Attaching a tty when you run the Docker image and allowing the permissions when prompted.
Inspecting the security permissions and accepting them (if appropriate) by adding the --batch flag to the plugin install command.
See Plugin managementfor more information.
You now have a test Elasticsearch environment set up. Before you startserious development or go into production with Elasticsearch, you must do some additionalsetup:

This section lists terms and definitions you should be familiar with before getting deeper into Docker. For further definitions, see the extensive glossary provided by Docker.
Container image: A package with all the dependencies and information needed to create a container. An image includes all the dependencies (such as frameworks) plus deployment and execution configuration to be used by a container runtime. Usually, an image derives from multiple base images that are layers stacked on top of each other to form the container's filesystem. An image is immutable once it has been created.
Dockerfile: A text file that contains instructions for building a Docker image. It's like a batch script, the first line states the base image to begin with and then follow the instructions to install required programs, copy files, and so on, until you get the working environment you need.
Brew Docker-machine-driver-xhyve
Build: The action of building a container image based on the information and context provided by its Dockerfile, plus additional files in the folder where the image is built. You can build images with the following Docker command:
Container: An instance of a Docker image. A container represents the execution of a single application, process, or service. It consists of the contents of a Docker image, an execution environment, and a standard set of instructions. When scaling a service, you create multiple instances of a container from the same image. Or a batch job can create multiple containers from the same image, passing different parameters to each instance.
Volumes: Offer a writable filesystem that the container can use. Since images are read-only but most programs need to write to the filesystem, volumes add a writable layer, on top of the container image, so the programs have access to a writable filesystem. The program doesn't know it's accessing a layered filesystem, it's just the filesystem as usual. Volumes live in the host system and are managed by Docker.
Tag: A mark or label you can apply to images so that different images or versions of the same image (depending on the version number or the target environment) can be identified.
Multi-stage Build: Is a feature, since Docker 17.05 or higher, that helps to reduce the size of the final images. In a few sentences, with multi-stage build you can use, for example, a large base image, containing the SDK, for compiling and publishing the application and then using the publishing folder with a small runtime-only base image, to produce a much smaller final image.
Docker Machine Xhyve Game
Repository (repo): A collection of related Docker images, labeled with a tag that indicates the image version. Some repos contain multiple variants of a specific image, such as an image containing SDKs (heavier), an image containing only runtimes (lighter), etc. Those variants can be marked with tags. A single repo can contain platform variants, such as a Linux image and a Windows image.
Registry: A service that provides access to repositories. The default registry for most public images is Docker Hub (owned by Docker as an organization). A registry usually contains repositories from multiple teams. Companies often have private registries to store and manage images they've created. Azure Container Registry is another example.
Multi-arch image: For multi-architecture, it's a feature that simplifies the selection of the appropriate image, according to the platform where Docker is running. For example, when a Dockerfile requests a base image mcr.microsoft.com/dotnet/sdk:5.0 from the registry, it actually gets 5.0-nanoserver-1909, 5.0-nanoserver-1809 or 5.0-buster-slim, depending on the operating system and version where Docker is running.
Docker Hub: A public registry to upload images and work with them. Docker Hub provides Docker image hosting, public or private registries, build triggers and web hooks, and integration with GitHub and Bitbucket.
Azure Container Registry: A public resource for working with Docker images and its components in Azure. This provides a registry that's close to your deployments in Azure and that gives you control over access, making it possible to use your Azure Active Directory groups and permissions.
Docker Trusted Registry (DTR): A Docker registry service (from Docker) that can be installed on-premises so it lives within the organization's datacenter and network. It's convenient for private images that should be managed within the enterprise. Docker Trusted Registry is included as part of the Docker Datacenter product. For more information, see Docker Trusted Registry (DTR).
Docker Community Edition (CE): Development tools for Windows and macOS for building, running, and testing containers locally. Docker CE for Windows provides development environments for both Linux and Windows Containers. The Linux Docker host on Windows is based on a Hyper-V virtual machine. The host for Windows Containers is directly based on Windows. Docker CE for Mac is based on the Apple Hypervisor framework and the xhyve hypervisor, which provides a Linux Docker host virtual machine on macOS X. Docker CE for Windows and for Mac replaces Docker Toolbox, which was based on Oracle VirtualBox.
Docker Enterprise Edition (EE): An enterprise-scale version of Docker tools for Linux and Windows development.
Compose: A command-line tool and YAML file format with metadata for defining and running multi-container applications. You define a single application based on multiple images with one or more .yml files that can override values depending on the environment. After you've created the definitions, you can deploy the whole multi-container application with a single command (docker-compose up) that creates a container per image on the Docker host.
Cluster: A collection of Docker hosts exposed as if it were a single virtual Docker host, so that the application can scale to multiple instances of the services spread across multiple hosts within the cluster. Docker clusters can be created with Kubernetes, Azure Service Fabric, Docker Swarm and Mesosphere DC/OS.
Docker Machine Xhyve Tool
Orchestrator: A tool that simplifies management of clusters and Docker hosts. Orchestrators enable you to manage their images, containers, and hosts through a command-line interface (CLI) or a graphical UI. You can manage container networking, configurations, load balancing, service discovery, high availability, Docker host configuration, and more. An orchestrator is responsible for running, distributing, scaling, and healing workloads across a collection of nodes. Typically, orchestrator products are the same products that provide cluster infrastructure, like Kubernetes and Azure Service Fabric, among other offerings in the market.

Using Enhanced Mode Ubuntu 18.04 for Hyper-V on Windows 10
I run Windows as my daily driver but I use WSL (Windows Subsystem for Linux) all day long but WSL is just the command-line and has some perf issues with heavy file system work. I use Docker for Windows which works amazingly and has it good perf but sometimes I want to test on a full Ubuntu Desktop.
ASIDE: No joke. My Linux/Ubuntu bona fides go back a while. Here's me installing Ubuntu 10.4 on Windows 7 over 8 years ago. Umuntu ngumuntu ngabantu!
To be frank, historically Ubuntu has sucked on Window's Hyper-V. If you wanted to get a higher (read: usable) resolution it would take a miracle. If you wanted shared clipboards or shared disk drives, well, again, miracle or a ton of manual set up. It's possible but it's not fun.
Why can't it be easy? Well, it is. I installed the Windows 10 "Fall Creators Update" - yes the name is stupid. It's Windows 10 "1809" - that's 2018 and the 9th month. Just type "Winver" from the Start menu. You may have "1803" from March. Go update.
Windows 10 includes Hyper-V Quick Create which has this suspiciously short list under "Select an operating system." Anytime a list has 1 or 2 items and some whitespace that means it will someday have n+1 list items.
Recently Ubuntu 18.04.1 LTS showed up in this list. You can quickly and easily create an Ubuntu VM from here and it's all handled, downloading, network switch, VM create, etc.
I dig it. So click create, start it up...get to the set up screen. Now, here, make sure you click "Require my password to login." What we want to do won't work with "Log in Automatically" and you don't want that anyway.
After you've created your VM and got it mostly setup, close the Hyper-V client window. Just X it out. The VM is still running of course.
Go over to Hyper-V Manager and right click on it and "Connect."
You'll see a resolution dialog...pick one! Go crazy! Do be aware that there are issues on 4k display but you can adjust within Ubuntu itself.
Now, BEFORE you click Connect, click "Show Options" and then "Local Resources." Under here, uncheck Smart Cards and Check "Drives."
Click OK and Connect...and you get this weird dialog! You're actually RDP'ing into Ubuntu! Rather than using the historical weird Hyper-V Client stuff to talk to Ubuntu and struggle with video cards and resolutions, here you are literally just Remote Desktoping into Ubuntu using integrated open source xrdp!
Login with your name and password (remember before when I said don't automatically login? This is why.)
What about Dynamic Resizing?
Here's an even better possible future. What we REALLY want (don't we, Dear Reader) is Dynamic Resolution and Resizing without Reconnection! Today you can just close and reconnect to change resolutions but I'd love to just resize the Ubuntu window like I do Windows 7/8/10 VM client windows.
The feature "Dynamic resolution update" was introduced in RDP 8.1. It enables to resize screen resolution on-the-fly.
Since we are using xrdp and that's open source over https://github.com/neutrinolabs/xrdp/ AND there's even a issue about this AND a lovely person has the code in their own branch and agreed to possibly upstream it maybe we can start using it and this great feature will just light up for folks who use Hyper-V Quick Create. Certainly we're talking weeks and months here (unless you want to help) but the lion's share of the work is done. I'm looking forward to resizing Ubuntu VMs dynamically.
What's in Enhanced Mode Today?
Back to today! You can read about how Linux VMs (Ubuntu or Arch) are set up in this GitHub repo https://github.com/Microsoft/linux-vm-tools You can set them up yourself with scripts, but the nice thing about Hyper-V Quick Create is that the work is done for us to make these "enhanced session" RDP-friendly VMs. No need to fear, you can just read the scripts yourself.
I can connect quickly and Enhanced Mode VMs give me:
a shared clipboard
the resolution of my choice on connect
fast painting/video/scrolling
automatic shared-drives
Smooth and automatic mouse capture
Fantastic.
What about installing Visual Studio Code? Of course. And also .NET Core.NET Core, natch.
This took like 10 min and 8 of it was waiting for Hyper-V Create to download Ubuntu. Try it out!
