Description Iryna Shcherbina 2018-02-05 17:36:11 UTC 
The muse RPM requires both Python 2 and Python 3:

$ dnf repoquery --disablerepo=* --enablerepo=rawhide --requires muse | grep python
/usr/bin/python2
/usr/bin/python3

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/python2" shebang in a Python 3 package can
introduce a Python 2 dependency. There is a section on shebangs in the Python RPM Porting Guide [0] which covers this issue.

Considering that muse Python scripts were switched to Python 3 in release 3.0pre1 according to changelog [1], can the package be switched to Python 3?


It's ok to do this in Rawhide only, however, it would be greatly
appreciated if you could push it to Fedora 27 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!

Hi Iryna, thanks for the report.

> Except in very special circumstances, there is no need for one package

I think this is one of those exceptional circumstances since not all the scripts are converted to Python3 upstream. e.g.
    https://github.com/muse-sequencer/muse/tree/master/muse3/utils/muse-song-convert.py
is clearly Python2, while the remaining scripts are Python3, e.g.
    https://github.com/muse-sequencer/muse/tree/master/muse3/share/scripts

At this point it is accurate to have both Python2 and Python3 dependencies. However I agree that this is not ideal. Let me see what I can do upstream.
Comment 2 Iryna Shcherbina 2018-02-06 09:00:02 UTC 
Hi Orcan, thank you for the update. You are right, some scripts are still Python 2. Lets then leave this bug open for tracking until it is ported upstream.
Comment 3 Fedora End Of Life 2018-02-20 15:22:09 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
