Uses deprecated distutils

[Ross Burton]

distutils is deprecated in Python 3.10 and will be *removed* in 3.12:

The easiest port is to setuptools, but the entirely custom install function makes the migration not as trivial as simply changing the import from distutils to setuptools.

Thanks for the report! :)

A related bug: wheels built by ufw don't work, as you have a custom install command.

You can test this by 'setup.py bdist_wheel' and then 'pip install ufw.wheel'. Almost everything is installed into the wrong places.

Update: I've been talking to the Python Packaging Authority and they basically say that if you want to install files outside of a Python module or the limited files they support then use a non-Python build system like autotools/Meson/etc.

"Given that setup.py install is deprecated and will not be un-deprecated, developers of Python software that performs Unixy integration are advised to migrate to a non-python build system."

The current setup.py is ancient. I need to take a hard look at it and survey my options. My priorities are to have a similar if not equivalent install experience (quite a few distros package ufw) while also doing the right thing wrt Debian python packaging. Any other niceties for development I can just change as needed. Thanks for the additional info.

Personally I’d say just port to Meson. It installs python nicely and works well with distribution tooling.

In the immediate short-term, Trevor's patch at least silences warnings for now.
