reopen 894075 found 894075 0.580-1 thanks As it turns out pkg_resources is not in distutils anymore (I'd have thought the same thing), but in python3-pkg-resources. Hence mypy still fails to run when installed on a system with minimal dependencies installed as evidenced by [0].
Kind regards Philipp Kern [0] https://salsa.debian.org/pkern/pybuildd/-/jobs/11056
