Hi Fred,

your code works for me without printing any warnings.

The important thing is that you never use pip to install anything into Fedora's site-packages /usr/lib64/python3.9/site-packages/ . That can (and will) cause a lot of trouble. Use "dnf" only to install stuff into your system site-packages directory. Use virtualenvs (or similar mechanisms) to install your own libraries with pip.

Actually I see a lot of bug reports about certbot in Fedora/EPEL where users installed custom Python libraries which break Fedora's certbot. For Python packages included in Fedora we can check that everything works fine (though sometimes a bug might go unnoticed).


I suggest you revert all manual changes first, reinstall all Python packages and then create a custom virtualenv if you need additional libraries:

$ rpm -qf /usr/lib64/python3.9/site-packages/* | grep 'is not owned by any 
package'
-> you will see a list of files/directories which are not part of Fedora's
   packages. You should delete those.

Once you did that, check all remaining Python packages which might have been replaced by pip:
$ rpm -qf /usr/lib64/python3.9/site-packages/* | xargs rpm --verify

You'll see a list of changed files, e.g.:
S.5....T.    /usr/share/glib-2.0/schemas/gschemas.compiled

If these files are in /usr/lib64/python3.9/site-packages/ you can check which python package these belong to ("rpm -qf /path/to/file") and reinstall those packages using "dnf reinstall ...".

Once you have done that you Fedora system should be fine again and you can start using virtualenvs.

Felix
