Thanks for updating, but I still get failures. And I asked pytest
upstream about possible fixes of the 3.X branch, which they are not
going to do:

The current failure in python-astropy is

E   UsageError: Plugin specs must be a ','-separated string or a
list/tuple of strings for plugin names. Given: 

which blocks the whole suite. Other packages have errors that really
look strange (data files are missing, submodules not found etc). Sure,
that all could be workarounded somehow, but in a few weeks the next
update of a dependency may make trouble again.

We will publish Debian Buster not earlier than summer/fall next year,
and this is just ~6-9 months before Python 2 EOL. I don't want to put
too many efforts in keeping this alive.

Best

Ole

according to linked issue, that bug is fixed in 3.10.1, which is in Debian
unstable now.

maybe just disable some of that tests? Not whole testsuite?

Thanks, however it turns out that this will unfortunately not work for
me: from astropys POV, pytest seems to be broken in versions 3.7 - 3.10;
see

https://github.com/astropy/astropy/issues/8177

I also observed diverse failures on other (astropy dependent) packages
with 3.10. Which basically means that I need to switch off the tests,
unless pytests upstream provides a bugfixed 3.X version.

However, it seems that I need to start with the removal of the Python 2
astropy ecosystem, which may be in any case not the worst decision.
Personally, I like to put pressure to move towards Python 3.

Cheers

Ole

Hi,

my plan is:

   - keep 3.x for Buster
   - upgrade to >= 4.x just after Buster release

Because we are going to drop Python after Buster release, I think it's
perfectly fine that Astropy (Py2 version) will not support Pytest 4.x.
