Description Iryna Shcherbina 2018-02-19 16:28:58 UTC 
The python3-tw2-core (2.2.3-9.fc28) RPM requires both Python 2 and Python 3:

$  dnf --disablerepo=* --enablerepo=rawhide repoquery --requires python3-tw2-core | grep python
/usr/bin/python2
python(abi) = 3.6
...

This happened due to recently introduced shebangs mangling [0], and you might see the warnings in the build log:

> + /usr/lib/rpm/redhat/brp-mangle-shebangs
> *** WARNING: mangling shebang in ./usr/lib/python3.6/site-packages/tw2/core/testbase/xhtmlify.py from #!/usr/bin/env python to #!/usr/bin/python2. This will become an ERROR, fix it manually!

The executable contains `#!/usr/bin/env python` shebang, which is forbidden by the guidelines and is automatically mangled to `#!/usr/bin/python2` during build. Please fix the shebang to be `#!/usr/bin/python3` explicitly [1] or remove the executable bit from the above file if not needed.

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!

Comment 1 Fedora End Of Life 2018-02-20 15:38:02 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
