This is a tracking bug for Change: Retire python3.5
For more details, see: https://fedoraproject.org/wiki/Changes/RetirePython3.5
The python3.5 package will be retired without replacement from Fedora 35. Python 3.5 has been End of Life since September 2020 and was kept around only to test software targeting Ubuntu 16.04 “Xenial Xerus” LTS and Debian 9 “Stretch” LTS. The removal is more or less aligned with Debian 9 EOL (2022-06-30) -- Fedora 34 EOLs on 2022-05-17. Ubuntu 16.04 LTS EOLs sooner, in April 2021.
Not before branching.
Also, I'd rather do this as late as possible same as with Python 3.4. We might benefit of the CI tests on Python 3.5 in rawhide if we ever backport some changes from rawhide to Fedora 34 (or even 33/32).
Hence, my plan is to retire python3.5 right before the Fedora 35 branching (August 2021) or sooner if it fails to install for some reason (beyond a reasonable fix).
