When I run "borgbackup" the command fails with a traceback as the "requires.txt" file (/usr/lib64/python3.6/site-packages/borgbackup-1.1.7-py3.6.egg-info/requires.txt) lists: msgpack-python!=0.5.0,!=0.5.1,!=0.5.2,!=0.5.3,!=0.5.4,!=0.5.5,<=0.5.6,>=0.4.6 I think that should by only "msgpack" (which is the name of the Python module, only the RPM is named "python3-msgpack"). Also we can maybe think about the very specific version requirements. AFAIK Fedora's tooling won't prevent a push of "python3-msgpack 0.5.7" but that would break borg again.
