How to Enable Backports on Debian Linux 12/11/10
Last Updated on by Joshua James
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 However, one common drawback is that packages in Debian can become outdated, especially as a new release ages.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.list file 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-firmware
deb-src http://deb.debian.org/debian bookworm-backports main contrib non-free-firmware
Debian 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-free
Debian 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 with CTRL+X.
Update the repository list by running the following command:
sudo apt update
Alternative Enable Backports on Debian Method
An alternative add Debian backports to your sources list, you can use the echo command along with the tee command. The tee command is used to read from standard input and write to standard output and files. This method will help you avoid having to use a text editor and do this directly from the command line.
For Debian 12 Bookworm, the command would be:
echo "deb http://deb.debian.org/debian bookworm-backports main contrib non-free-firmware" | sudo tee -a /etc/apt/sources.list
For Debian 11 Bullseye, the command would be:
echo "deb http://deb.debian.org/debian bullseye-backports main contrib non-free" | sudo tee -a /etc/apt/sources.list
For Debian 10 Buster, the command would be:
echo "deb http://deb.debian.org/debian buster-backports main non-free" | sudo tee -a /etc/apt/sources.list
Then run an APT update:
sudo apt update
Installing 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:
For example, to install Cockpit on Debian 11 using the backports repository, run the following command:
sudo apt install cockpit -t bullseye-backports
This command will install the newer Cockpit version available in the backports repository, providing 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.list configuration 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 with CTRL+X.
Update the repository list by running the following command:
sudo apt update
Now, 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 experimental
Installing 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 experimental
Caution: 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.
