Docker Repository Does Not Have a Release File on Running apt-get update on Ubuntu

I am using Ubuntu 16.10 and recently installed Docker (v1.12.4) using the Xenial build by following the instructions found here. I haven’t encountered any problems creating containers, ensuring they restart automatically, etc.

However, now every time I run apt-get update I receive the following error message:

I have tried to remedy the problem by following the advice found here and cannot seem to solve this problem.

Has anyone encountered this before and fixed it? If so, what is needed to resolve this?

On Linux Mint, the official instructions did not work for me. I had to go into /etc/apt/sources.list.d/additional-repositories.list and change serena to xenial to reflect my Ubuntu codename. Depending on your Debian variant, version, and the original installation method followed, you may need to modify /etc/apt/sources.list.d/docker.list instead.

You can typically find the appropriate codename by running one of a few different commands. In the following examples, focal is the codename:

For Linux Mint, this problem is actually referenced in the Docker website:

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial . Sometimes, in a distribution like Linux Mint, you might have to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Rafaela, you could use trusty.

$ sudo add-apt-repository \
«deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable»

The lsb_release -cs command gives a repository for which Docker has no prepared package — you must change it to xenial.

Elliot Beach is correct. Thanks Elliot.

Here is the code from my gist.

As suggested in official docker document also. Try running this:

Then remove/comment any ( deb [arch=amd64] https://download.docker.com/linux/ubuntu/ xenial stable ) such entry at the last lines of the file.

Then in terminal run this command:

sudo add-apt-repository «deb [arch=amd64] https://download.docker.com/linux/ubuntu/ bionic stable»

sudo apt-get update

It worked in my case.

Linux Mint 20 Ulyana users need to change «ulyana» to «bionic» in

I saw an interesting post from Ikraider here that solved my issue : https://github.com/docker/docker/issues/22599

Website instructions are wrong, here is what works in 16.04:

I was facing similar issue on Linux mint what I did was found out Debian version using,

$ cat /etc/debian_version buster/sid

then replaced Debian version in

I also had a similar issue. Someone might find what worked for me helpful.

Machine is running Ubuntu 16.04 and has Docker CE. After looking through the answers and links provided here, especially from the link from the Docker website given by Elliot Beach, I opened my /etc/apt/sources.list and examined it.

The file had both deb [arch=amd64] https://download.docker.com/linux/ubuntu (lsb_release -cs) stable and deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable .

Since the second one was what was needed, I simply commented out the first, saved the document and now the issue is fixed. As a test, I went back into the same document, removed the comment sign and ran sudo apt-get update again. The issue returned when I did that.

So to recap : not only did I have my parent Ubuntu distribution name as stated on the Docker website but I also commented out the line still containing (lsb_release -cs).

Install Docker Engine on Ubuntu

Estimated reading time: 12 minutes

Docker Desktop for Linux

Docker Desktop helps you build, share, and run containers easily on Mac and Windows as you do on Linux. Docker handles the complex setup and allows you to focus on writing the code. Thanks to the positive support we received on the subscription updates, we’ve started working on Docker Desktop for Linux which is the second-most popular feature request in our public roadmap. If you are interested in early access, sign up for our Developer Preview program.

To get started with Docker Engine on Ubuntu, make sure you meet the prerequisites, then install Docker.

Prerequisites

OS requirements

To install Docker Engine, you need the 64-bit version of one of these Ubuntu versions:

• Ubuntu Hirsute 21.04
• Ubuntu Focal 20.04 (LTS)
• Ubuntu Bionic 18.04 (LTS)

Docker Engine is supported on x86_64 (or amd64 ), armhf , arm64 , and s390x architectures.

Ubuntu 16.04 LTS “Xenial Xerus” end-of-life

Ubuntu Linux 16.04 LTS reached the end of its five-year LTS window on April 30th 2021 and is no longer supported. Docker no longer releases packages for this distribution (including patch- and security releases). Users running Docker on Ubuntu 16.04 are recommended to update their system to a currently supported LTS version of Ubuntu.

Uninstall old versions

Older versions of Docker were called docker , docker.io , or docker-engine . If these are installed, uninstall them:

It’s OK if apt-get reports that none of these packages are installed.

The contents of /var/lib/docker/ , including images, containers, volumes, and networks, are preserved. If you do not need to save your existing data, and want to start with a clean installation, refer to the uninstall Docker Engine section at the bottom of this page.

Supported storage drivers

Docker Engine on Ubuntu supports overlay2 , aufs and btrfs storage drivers.

Docker Engine uses the overlay2 storage driver by default. If you need to use aufs instead, you need to configure it manually. See use the AUFS storage driver

Installation methods

You can install Docker Engine in different ways, depending on your needs:

Most users set up Docker’s repositories and install from them, for ease of installation and upgrade tasks. This is the recommended approach.

Some users download the DEB package and install it manually and manage upgrades completely manually. This is useful in situations such as installing Docker on air-gapped systems with no access to the internet.

In testing and development environments, some users choose to use automated convenience scripts to install Docker.

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

Set up the repository

Update the apt package index and install packages to allow apt to use a repository over HTTPS:

Add Docker’s official GPG key:

Use the following command to set up the stable repository. To add the nightly or test repository, add the word nightly or test (or both) after the word stable in the commands below. Learn about nightly and test channels.

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial . Sometimes, in a distribution like Linux Mint, you might need to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Tessa , you could use bionic . Docker does not offer any guarantees on untested and unsupported Ubuntu distributions.

Install Docker Engine

Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

Got multiple Docker repositories?

If you have multiple Docker repositories enabled, installing or updating without specifying a version in the apt-get install or apt-get update command always installs the highest possible version, which may not be appropriate for your stability needs.

To install a specific version of Docker Engine, list the available versions in the repo, then select and install:

a. List the versions available in your repo:

b. Install a specific version using the version string from the second column, for example, 5:18.09.1

Verify that Docker Engine is installed correctly by running the hello-world image.

This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.

Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Linux postinstall to allow non-privileged users to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine

To upgrade Docker Engine, first run sudo apt-get update , then follow the installation instructions, choosing the new version you want to install.

Install from a package

If you cannot use Docker’s repository to install Docker Engine, you can download the .deb file for your release and install it manually. You need to download a new file each time you want to upgrade Docker.

Go to https://download.docker.com/linux/ubuntu/dists/ , choose your Ubuntu version, then browse to pool/stable/ , choose amd64 , armhf , arm64 , or s390x , and download the .deb file for the Docker Engine version you want to install.

To install a nightly or test (pre-release) package, change the word stable in the above URL to nightly or test . Learn about nightly and test channels.

Install Docker Engine, changing the path below to the path where you downloaded the Docker package.

The Docker daemon starts automatically.

Verify that Docker Engine is installed correctly by running the hello-world image.

This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.

Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Post-installation steps for Linux to allow non-privileged users to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine

To upgrade Docker Engine, download the newer package file and repeat the installation procedure, pointing to the new file.

Install using the convenience script

Docker provides a convenience script at get.docker.com to install Docker into development environments quickly and non-interactively. The convenience script is not recommended for production environments, but can be used as an example to create a provisioning script that is tailored to your needs. Also refer to the install using the repository steps to learn about installation steps to install using the package repository. The source code for the script is open source, and can be found in the docker-install repository on GitHub.

Always examine scripts downloaded from the internet before running them locally. Before installing, make yourself familiar with potential risks and limitations of the convenience script:

• The script requires root or sudo privileges to run.
• The script attempts to detect your Linux distribution and version and configure your package management system for you, and does not allow you to customize most installation parameters.
• The script installs dependencies and recommendations without asking for confirmation. This may install a large number of packages, depending on the current configuration of your host machine.
• By default, the script installs the latest stable release of Docker, containerd, and runc. When using this script to provision a machine, this may result in unexpected major version upgrades of Docker. Always test (major) upgrades in a test environment before deploying to your production systems.
• The script is not designed to upgrade an existing Docker installation. When using the script to update an existing installation, dependencies may not be updated to the expected version, causing outdated versions to be used.

Tip: preview script steps before running

You can run the script with the DRY_RUN=1 option to learn what steps the script will execute during installation:

This example downloads the script from get.docker.com and runs it to install the latest stable release of Docker on Linux:

Docker is installed. The docker service starts automatically on Debian based distributions. On RPM based distributions, such as CentOS, Fedora, RHEL or SLES, you need to start it manually using the appropriate systemctl or service command. As the message indicates, non-root users cannot run Docker commands by default.

Use Docker as a non-privileged user, or install in rootless mode?

The installation script requires root or sudo privileges to install and use Docker. If you want to grant non-root users access to Docker, refer to the post-installation steps for Linux. Docker can also be installed without root privileges, or configured to run in rootless mode. For instructions on running Docker in rootless mode, refer to run the Docker daemon as a non-root user (rootless mode).

Install pre-releases

Docker also provides a convenience script at test.docker.com to install pre-releases of Docker on Linux. This script is equivalent to the script at get.docker.com , but configures your package manager to enable the “test” channel from our package repository, which includes both stable and pre-releases (beta versions, release-candidates) of Docker. Use this script to get early access to new releases, and to evaluate them in a testing environment before they are released as stable.

To install the latest version of Docker on Linux from the “test” channel, run:

Upgrade Docker after using the convenience script

If you installed Docker using the convenience script, you should upgrade Docker using your package manager directly. There is no advantage to re-running the convenience script, and it can cause issues if it attempts to re-add repositories which have already been added to the host machine.

Uninstall Docker Engine

Uninstall the Docker Engine, CLI, and Containerd packages:

Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

You must delete any edited configuration files manually.
