Bug#1020091: diffoscope: FTBFS: RuntimeError: 'distutils.core.setup()' was never called -- perhaps 'setup.py' is not a Distutils setup script?

Source: diffoscope
Version: 221

Hi,

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


Relevant part (hopefully):

> <string>:1: DeprecationWarning: The distutils package is deprecated and slated for removal in Python 3.12. Use setuptools or check PEP 632 for potential alternatives
> /usr/lib/python3/dist-packages/_distutils_hack/__init__.py:18: UserWarning: Distutils was imported before Setuptools, but importing Setuptools also replaces the `distutils` module in `sys.modules`. 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.
