Comment 3 Miro Hrončok 2020-07-09 13:34:12 UTC
Upstream doesn't support Python 2.7. If this gets fixed in RHEL, Fedora can take the fix from there.

Comment 4 Miro Hrončok 2020-07-20 23:20:28 UTC
There is no ipaddress module in python27.

There is a bundled ipaddress backport library bundled in pip bundled in Python 2.7.

Pip does not have dictionaries containing IPv4Interface or IPv6Interface objects. I don't think it's worth patching the bundled ipaddress module in it.
