Description Tomas Orsava 2016-06-03 11:39:52 UTC

The cantor RPM requires both Python 2 and Python 3.

Except in very special circumstances, there is no need for one package
to drag in both Python stacks. Usually, this is a packaging error: for
example, a stray "/usr/bin/python" shebang in a Python 3 package can
introduce a Python 2 dependency.

Please split your package, or remove the stray dependencies.
There is a section on shebangs in the Python RPM Porting Guide [0]
which covers this issue.

It's ok to do this in Rawhide only, however, it would be greatly
appreciated if you could push it to Fedora 24 as well.


If anything is unclear, or if you need any kind of assistance, you can
ask on IRC (#fedora-python on Freenode), or reply here. We'll be happy
to help investigating or fixing this issue!
