pythonnet

• Docs: ? ! Developers recommend Mono version 5.20.1 ^{Issues 939} On Ubuntu, the eoan universe repository has to be added

deb https://archive.ubuntu.com/ubuntu/ eoan universe
deb https://archive.ubuntu.com/ubuntu/ eoan-updates universe

But I can't figure out how to add the older version, because the recommended syntax produces the error "Unable to correct problems, you have held broken packages"

sudo apt install mono-devel=5.18.0.240+dfsg-3

Maybe try the tarballs on Mono's website... Or maybe there's another repo I don't know about..

apt install clang libglib2.0-dev python3-dev

pip install pycparser pythonnet
pip install -U setuptools
