[Debian-pan-maintainers] Bug#1022440: Bug#1022440: python-fabio: FTBFS: distutils.errors.DistutilsClassError: command class <class '__main__.CleanCommand'> must subclass Command

[Jerome Kieffer]

Dear Lucas,

I suspect the issue is once again the "numpy.distutils" which enforces "setuptools<60"...
I have started to port FabIO to the meson-python builder, in a similar
way to what is done for scipy-1.9 (still not packaged for debian).
It is now close to production ready and can release a version as soon
the packaging tools are available in debian.

Best regards,

Jérôme Kieffer

This may lead to undesirable behaviors or errors. To avoid these issues, avoid using distutils directly, ensure that setuptools is installed in the traditional way (e.g. not an editable install), and/or make sure that setuptools is always imported before distutils.
