How exactly does the build fail?

I'd like to be able to give a better answer but I'm not entirely sure
that the script works with python3 without any other changes.  It looks
like it should but I don't have a trivial way of testing it (or time to
setup a test environment).

Given that /usr/bin/python isn't supported anymore, we might as well
change it as above see what bug reports get generated.

If you're keen to improve the script then you could try to clean it up
and get rid of warnings from pylint and flake8.  getting rid of the
obvious whitespace issues might make any python3 issues more obvious.
Perhaps yapf3 would be useful?

peace & happiness,
