Adding the “Backports” Repository

To add the backports repository, the following file was created:

sudo nano /etc/apt/sources.list.d/backports.list

Inside that file, add this:

deb http://deb.debian.org/debian bookworm-backports main

To install a package from that repository, add the -t option, like this:

sudo apt install -t bookworm-backports package-name 

tldr
