It can be switched to Python 3 by changing the Build-Dependency to python3-dev and passing PYTHON=python3 to configure. However, that seems to require a soname change (especially because the current one was also used in buster), so what do we do, custom soname until the next time upstream bumps it?

I pushed the changes to the git repo. I could use some help figuring out the reasons for the ~126 failing doctests.

Another issue is that the build log is 25 MB big because the docbuild prints this message all over:

RemovedInSphinx20Warning: formatargspec() is now deprecated.  Please use sphinx.util.inspect.Signature instead.

Best,
