You can remove all of the python-oslo* from the list. The versions in
Experimental, which are the next version of OpenStack, are fixed. In 2
weeks of time, I'll upload all what I staged in Experimental to Sid
(maybe 150 packages?) and that's going to fix it all.

For the others, probably I should start filling bugs...

I really don't know about pypy. Probably the pypy-pytest should indeed
go away, as the initial plan was to switch to pypy3. Maybe tumbleweed
(Stefano Rivera) would be able to answer. I'm adding him as Cc.

So, if I'm following correctly, what you seem to propose, is to remove
Python 2 from unittest2. If that's the case, then I agree with such a
plan. I just didn't dare to do it yet.

Though in fact, I already worked on that, but stopped, also because
unittest2 FTBFS when I try building it on my laptop. So I've pushed it
in its normal Git repo [1] under a py2-removal branch. If anyone has
some time available to look at it, that'd be nice (I currently don't...).
