APT /etc/apt/sources.list for every Debian release
Debian uses APT as package installation and update manager. This also applies to a distribution (release) upgrade. Usually not much changes in the APT configuration, except the code name. But sometimes, the /etc/apt/sources.list file needs some adjustments for a different release. This is where this list comes to help.
If you want to add the "backports" repositories, read our related article How to enable Debian backports repositories.

Oh you precious human being! I have been going in circles ALL DAY trying to figure out what I originally did wrong to make my machine go stupid. Then I made it worse! Can I just go into my sources.list, delete all the lines and then come back and paste the .list above (Debian Bullseye) back in there? Or do I need to do a bunch of other things as well (PLEASE tell me it's as simple as erase, paste, save, exit!). Thanks!
Yes, you can. Followed by a
apt-get updateof course.Thanks! It worked for my installation of Debian 11.
