Conflicts between Ubuntu 20.04 packages and Debian 11 packages

Solution 1:

Your PPA list is not reasonable. You are not expected to mix in Debian repositories with Ubuntu repositories, because both operating systems are binary incompatible, even though Ubuntu is based of Debian.

Remove these PPA's asap. Using inadapted repositories may heavily damage a system, even leading to a need to reinstall. Only add third party repositories if 1) there is no other option and 2) they are explicitly indicated to work with the specific Ubuntu version that you use.

Solution 2:

The problem is that you are mixing sources from different distributions.

This is a bad idea and will create conflicts and all sorts of other problems.

Don't mix sources from other distros or even from different versions of Ubuntu.
