• How To Install Backports on Debian 11 - idroot

  In this tutorial, we will show you how to install Backports on Debian 11. For those of you who didn’t know, Backports have recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates), so they will run without new libraries (wherever it is possible) on a stable Debian distribution. Backports are pinned to priority 100 using apt-pinning, ie they are only installed when explicitly requested. Otherwise, the package from stable takes precedence. A package that has been installed from the backports is updated from the backports.

  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).
