[Debian-astro-maintainers] Bug#1002410: astroplan: FTBFS: ImportError: cannot import name 'Sequence' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

[Lucas Nussbaum]

Source: astroplan
Version: 0.7-1
Severity: serious
Justification: FTBFS
Tags: bookworm sid ftbfs

Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> py3versions: no X-Python3-Version in control file, using supported versions
> xvfb-run -a python3.10 setup.py test
> Matplotlib created a temporary config/cache directory at /tmp/matplotlib-g_1na5hc because the default path (/sbuild-nonexistent/.config/matplotlib) is not a writable directory; it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.
