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

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have been replaced by pip: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.5T. /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
Well thank you very much. I know what to do now then. :-)

Python libraries problem with F34
Hello!
Not a developer but I do write code sometimes, and in Python most of the
times.
Some of my Python code/scripts which were running without any issue
until F33, no longer do with F34. I actually upgraded from F33 to F34.
I had issues with pexpect (which just now is working again...) and
requests/urllib. The requests issue is still here and while the code is
running I get this error:
"warnings.warn("urllib3 ({}) or chardet ({}) doesn't match a supported "
RequestsDependencyWarning: urllib3 (1.25.10) or chardet (4.0.0) doesn't
match a supported version!"
I assume it's a library mismatch but I'm not sure exactly what to do
about it and my interweb searches did manage to address the issue neither.
Any idea what could be wrong?
Thank you.
Fred
