[Debian-astro-maintainers] Bug#1027398: gavodachs: autopkgtest needs update for new version of python-cryptography: fails to install

Severity: serious

Dear maintainer(s),

With a recent upload of python-cryptography the autopkgtest of gavodachs 
fails in testing when that autopkgtest is run with the binary packages 
of python-cryptography from unstable. It passes when run with only 
packages from testing. In tabular form:

                        pass            fail
python-cryptography    from testing    38.0.4-1
gavodachs              from testing    2.7+dfsg-1
all others             from testing    from testing

I copied some of the output at the bottom of this report. 
gavodachs2-server fails to install.

Currently this regression is blocking the migration of 
python-cryptography to testing [1]. Of course, python-cryptography 
shouldn't just break your autopkgtest (or even worse, your package), but 
it seems to me that the change in python-cryptography was intended and 
your package needs to update to the new situation.

If this is a real problem in your package (and not only in your 
autopkgtest), the right binary package(s) from python-cryptography 
should really add a versioned Breaks on the unfixed version of (one of 
your) package(s). Note: the Breaks is nice even if the issue is only in 
the autopkgtest as it helps the migration software to figure out the 
right versions to combine in the tests.
