Frist of all, thank you for well described video! Though, if you try to run "sudo apt update", you can see that the final linking of python3 creates the problem of:

E: Problem executing scripts 'if /usr/bin/test -w /var/lib/command-not-found/ -a -e /usr/lib/cnf-update-db; then /usr/lib/cnf-update-db > /deess 'if /usr/bin/test -w /var/lib/command-not-found/ -a -e /usr/lib/cnf-update-db; then /usr/libv/null; fi'
E: Sub-process returned an error code

How did you solve this?
