Debian is renowned within the Linux community for its exceptional stability, often establishing itself as the gold standard among Linux distributions. However, one common drawback is that packages in Debian can become outdated, especially as a new release ages. These packages only receive security and bug updates to maintain stability, which can frustrate users who require specific package upgrades to access new features or address non-critical or non-security-related bugs. Thankfully, the flexibility of Linux and the use of repositories offer a solution: Debian backports and Debian experimental repositories.
Debian backports and experimental repositories are packages taken from the next Debian release, typically the testing repository, and recompiled for use on Debian stable. This tutorial will demonstrate:
- How to enable Debian backports: Learn to configure your Debian 12 Bookworm, Debian 11 Bullseye, or Debian 10 Buster desktop or server to access packages from backports.
- Searching and installing packages: Discover how to locate and install desired packages from Debian backports or Debian experimental repositories.
By following this tutorial, you can enhance your Debian 12 Bookworm, Debian 11 Bullseye, or Debian 10 Buster desktop or server with the latest packages while maintaining the stability you’ve come to expect from Debian.
Enabling the Backports Repository
The first step to installing packages from the backports repository is adding the repository to the sources.list file. Follow these steps to enable the backports repository on your Debian system:
- Open the terminal on your Debian system.
- Execute the command below to open the
sources.listfile with the nano text editor:
sudo nano /etc/apt/sources.list- Append the appropriate lines to the file based on your Debian version. Make sure to use the correct codename for your Debian distribution to avoid issues.
Debian 12 Bookworm backports
deb http://deb.debian.org/debian bookworm-backports main contrib non-free
deb-src http://deb.debian.org/debian bookworm-backports main contrib non-freeDebian 11 Bullseye backports
deb http://deb.debian.org/debian bullseye-backports main contrib non-free
deb-src http://deb.debian.org/debian bullseye-backports main contrib non-freeDebian 10 Buster backports
deb http://deb.debian.org/debian buster-backports main contrib non-free
deb-src http://deb.debian.org/debian buster-backports main contrib non-free- Save the configuration file by pressing
CTRL+O, and then exit withCTRL+X. - Update the repository list by running the following command:
sudo apt updateInstalling Packages from Backports
Using backports on Debian is straightforward; the syntax is similar to installing a standard package, except you’ll add the -t flag.
Search packages from Debian Backports
Use the following command to search for packages in the backports repository, replacing "package-name" with the desired package name:
- Debian 12 Bookworm example:
sudo apt search "package-name" -t bullseye-backports- Debian 11 Bullseye example:
sudo apt search "package-name" -t bullseye-backports- Debian 10 Buster example:
sudo apt search "package-name" -t buster-backportsInstalling or Upgrading Packages from Debian Backports
Use the following command to install or upgrade packages from the backports repository, replacing "package-name" with the desired package name:
- Debian 12 Bookworm example:
sudo apt install "package-name" -t bullseye-backports- Debian 11 Bullseye example:
sudo apt install "package-name" -t bullseye-backports- Debian 10 Buster example:
sudo apt install "package-name" -t buster-backportsLive Example: Installing Cockpit on Debian 11
For example, to install Cockpit on Debian 11 using the backports repository, run the following command:
sudo apt install cockpit -t bullseye-backportsThis command will install the newer version of Cockpit available in the backports repository, providing you with access to more up-to-date features.
Enabling the Experimental Repository
For those who want to live on the cutting edge, the experimental repository offers the most bleeding-edge updates from Debian. However, this repository should be used with caution and primarily on test systems or by developers and sysadmins who understand the risks and can handle potential issues. The experimental repository has a higher chance of incompatibilities and should not be used on live production servers or critical environments.
To enable the experimental repository, follow these steps:
- Re-open the
sources.listconfiguration file by running the following command:
sudo nano /etc/apt/sources.list- Add the following lines at the end of the file, after the lines you previously added for the backports repository:
deb http://deb.debian.org/debian experimental main contrib non-free
deb-src http://deb.debian.org/debian experimental main contrib non-free- Save the configuration file by pressing
CTRL+O, and then exit withCTRL+X. - Update the repository list by running the following command:
sudo apt updateNow, you can use the -t flag with the experimental keyword in your commands to search and install packages from the experimental repository.
Searching for Packages in the Experimental Repository
Use the following command to search for packages in the experimental repository, replacing "package-name" with the desired package name:
sudo apt search "package-name" -t experimentalInstalling Packages from the Experimental Repository
Use the following command to install packages from the experimental repository, replacing "package-name" with the desired package name:
sudo apt install "package-name" -t experimentalCaution: Be careful when using packages from the experimental repository, especially on live production servers or environments running critical services. The experimental repository is not recommended for general use due to the higher risk of incompatibilities and issues.
Conclusion
Enabling Debian backports and experimental repositories allows you to access and install newer packages on your Debian 12 Bookworm, Debian 11 Bullseye, or Debian 10 Buster system while maintaining its renowned stability. By following the tutorial outlined above, you can enhance your Debian experience by utilizing the latest packages, features, and bug fixes from the backports and experimental repositories.
