Comment 2 for bug 2072685

I can confirm that python3-pycallgraph from jammy-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 jammy-proposed to apt sources.
install python3-pycallgraph from jammy-proposed.

Followed the testplan and tried "pycallgraph --help" to confirm it works now.
Additionally follow the testplan from #2062065 and use the basic.py and confirmed it creates the two png files.

Package tested:

$ apt-cache policy python3-pycallgraph
python3-pycallgraph:
