Hi,

The log files that are attached indicate that the problem appears after you have run "apt purge python3.6-minimal". Therefore I don't think it is a bug in the python packages, because removing all Python interpreters from your installation is not expected.

You could try to find help for fixing your system using one of the methods listed there: https://community.ubuntu.com/t/community-support/709
