Then your sources.list file was incorrect to begin with. I'm guessing you had something like this: deb http://deb.debian.org/debian stable main contrib non-free You should never use the "stable" alias in the sources.list file, because it's a moving target. Doing an update/upgrade after a new version of Debian has released will try to pull in pieces of the new version, when you aren't prepared for it. Always use the codename of the Debian version that you intend to run. For example: deb http://deb.debian.org/debian buster main contrib non-free At this point, you have two basic choices: you can either finish upgrading to Debian 11, or you can reinstall Debian 10. Personally, I'd go with the first option, unless there is a compelling reason to remain on Buster. Standard advice applies -- read the Bullseye release notes and the NewInBullseye page on the wiki, make backups of your system first, and so on.
