When I run the automatic Ubuntu software update, I get the following message (see below). I installed Python 3.7 by myself when I install the OS : so I have python 3.8 and 3.7 in the same time on my pc. Until now, I had met no issue. Can you help me about the process I must follow please. It seems to be an issue with focal1 and focal3 version ?
The package system is broken
Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
