Problems

During ./GenerateProjectFiles.sh in the output there is "Python SDK not found"

Look like is needed package pythonnet installable via pip3 but it give the error:

error: option --single-version-externally-managed not recognized it seem a bug in mono that should be fixed from few days... waiting new version
Tryied different workaround like: python3 -m pip install -U wheel pip3 install -U setuptools

even installing from source /usr/bin/python3 -m pip install -U git+https://github.com/pythonnet/pythonnet --user

even compiling from git repo

git clone https://github.com/pythonnet/pythonnet
cd pythonnet/
python setup.py bdist_wheel

give an error:
