How To Install Backports on Debian 11

Install Backports on Debian 11

In this tutorial, we will show you how to install Backports on Debian 11. For those of you who didn’t know, Debian Backports is a repository that provides newer versions of packages from the testing and unstable branches of Debian for the current stable release. The primary purpose of Backports is to offer users access to more recent software without compromising the stability and security of their Debian 11 system.

When a package is “backported,” it means that the developers have taken a newer version of the software from the testing or unstable branch and adapted it to work with the current stable release of Debian. This process ensures that the package is compatible with the system libraries and dependencies, providing users with the benefits of newer features and bug fixes while maintaining the overall stability of the distribution.

Using Debian Backports is particularly useful when you need access to specific software versions that are not available in the main Debian repositories or when you require security updates for packages that have been superseded in the stable branch.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Backports on a Debian 11 (Bullseye).


Before proceeding with the installation of backports, ensure that your system meets the following requirements:

  • A server running one of the following operating systems: Debian 11.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Backports on Debian 11 Bullseye

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade
sudo apt install dirmngr ca-certificates software-properties-common gnupg gnupg2 apt-transport-https curl

Step 2. Installing Backports on Debian 11.

By default, Backports is not available on Debian 11 base repository. So, now run the following command below to add their respective repository manually on our Linux system:

sudo nano /etc/apt/sources.list

Add the following lines:

deb bullseye-backports main contrib non-free
deb-src bullseye-backports main contrib non-free

Once you add the repository to your Debian system, now install Backports using the following commands:

sudo apt update
sudo apt -t bullseye-backports upgrade

Step 3. Installing Packages from the Debian Backports Package Repository.

If you wish to install some specific package from the backport repository then you have manually specified the package. backport repo along with -t flag with an APT package manager.

sudo apt install "package-name" -t bullseye-backports

For example, install the latest version of Kernel for new features and driver support:

sudo apt install linux-image-amd64 -t bullseye-backports

To search for a package on the Debian backports package repository, run the following command:

apt-cache search package-name
