Comment # 1 on bug 1062084 from Carmen Bianca Bakker

`python-docker-py` has been renamed to `python-docker`.  The new package
obsoletes and provides the old one.  However, it obsoletes `python2-docker-py`,
NOT `python-docker-py`.  This is because of some magic in the specfile.  The
easiest fix is to change all packages that depend on
`python{2,3}-docker{,-py}`.

The best fix, however, would be to properly obsolete `python-docker-py`.  But
that involves Specfile magic that I don't possess.
