A problem occurred in a Python script. Here is the sequence of
function calls leading up to the error, in the order they occurred.

Thanks for the bugreport!

The profile that probably triggers this is /etc/apparmor.d/usr.sbin.mysqld

My guess is that this file is empty or contains only comments - at least I can reproduce the problem when using such a file. Can you please confirm that your /etc/apparmor.d/usr.sbin.mysqld indeed only contains comments? (Or simply attach it ;-)

Dear Christian,

thank you for the quick analysis.

Oh how embarrassing, 8-)
you are absolutely right. The file only contains text.

I think this is not a bug in apparmor but maybe in the python script.

Best wishes for you and thanks again

Detlev
