(Get the code!)
Reproduced in a Debian container, so it's not Fedora-specific at least. Identical output to Kashyap's:
INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime. See https:/

INFO: pip is looking at multiple versions of pycodestyle to determine which version is compatible with other requirements. This could take a while.

# cat /etc/debian_version
11.3
# python3 --version
Python 3.9.2
# pip3 --version
pip 20.3.4 from /usr/lib/
# pip3 show tox
Name: tox
Version: 3.25.0
Exact same thing on Fedora 33 and 36 containers (pulled 33 first on accident, free data point).
33:
[root@782408867bf9 /]# python3 --version
Python 3.9.7
[root@782408867bf9 /]# pip3 --version
pip 20.2.2 from /usr/lib/
[root@782408867bf9 /]# pip3 show tox
Name: tox
Version: 3.25.0
36:
[root@699feac13be5 /]# python3 --version
Python 3.10.4
[root@699feac13be5 /]# pip3 --version
pip 21.3.1 from /usr/lib/
[root@699feac13be5 /]# pip3 show tox
Name: tox
Version: 3.25.0
UBI python-38 works!
# python3 --version; pip3 --version; pip3 show tox
Python 3.8.12
pip 21.2.3 from /opt/app-
Name: tox
Version: 3.25.0
UBI python-39 breaks:
# python3 --version; pip3 --version; pip3 show tox
Python 3.9.7
pip 21.2.3 from /opt/app-
Name: tox
Version: 3.25.0
So it looks like all my attempts on Python 3.9/3.10 broke but the one on 3.8 worked. There doesn't seem to be a correlation with the pip/tox version, but maybe it could be a weird interaction between specific versions of all of them?
Sean mentioned it working with 3.10 on Ubuntu and Nixos so worth trying those.
