Well, in the meantime, you uploaded a new version of python-setuptools, so the
Breaks/Replaces that already exists in python-pip is now out of date. But if
you agree to remove python-setuptools-whl in 20.0-3, I will update the B/R in
python-pip to match it.

Okay, but it was discussed fairly extensively in debian-python@ already, both
in terms of the technology and the changes in Debian Python Policy, which are
already committed to its vcs. But to re-iterate:
Through the use of dirtbike, packages which require -whls will build them at
their own build-time, but this is limited to pip and virtualenv. Because the
dependencies of upstream pip change, this is the only viable option for
sustainability. Thus the previous -whl packages sprinkled throughout the
archive should now be removed.
I've included the patch here. I'm not going to play whack-a-mole with this
bug, but it will be fixed when python-setuptools-whl is removed.

An optimal solution would consist in only one of the packages installing that file, and renaming or removing the file in the other package. Depending on the circumstances you might also consider Replace relations or file diversions. If the conflicting situation cannot be resolved then, as a last resort, the two packages have to declare a mutual Conflict. Please take into account that Replaces, Conflicts and diversions should only be used when packages provide different implementations for the same functionality. Here is a list of files that are known to be shared by both packages (according to the Contents file for sid/amd64, which may be slightly out of sync): /usr/share/python-wheels/setuptools-20.0-py2.py3-none-any.whl This bug has been filed against both packages. If you, the maintainers of the two packages in question, have agreed on which of the packages will resolve the problem please reassign the bug to that package.
