I can confirm that python3-pycallgraph from focal-proposed has fixed the bug for me.
Test done: install python3-pycallgraph and try to execute "pycallgraph --help" and confirmed that it still fails. Added focal-proposed to apt sources. install python3-pycallgraph from focal-proposed. Followed the testplan and try "pycallgraph --help". Additionally follow the testplan from #2062065 and use the basic.py and confirmed it creates the two png files.
