In general Python 3.8 should be fine. The test suite passes for us in Fedora
32 (which uses 3.8 as well) and even Python 3.9 (Fedora 33) works (IIRC).

Latest Fedora builds for borgbackup 1.1.11:

Fedora 33:
https://koji.fedoraproject.org/koji/buildinfo?buildID=1475335

Fedora 32:
https://koji.fedoraproject.org/koji/buildinfo?buildID=1475336

If you are looking for exact library versions used in Fedora maybe Koschei
could help:
