Again not working Ubuntu 20.04

[HakkaTjakka]

Ubuntu 20.04
Python 2 (after cleaning up .local)
Python 3 (after cleaning up .local)

pip install git+https://github.com/agermanidis/autosub.git (after cleaning up .local)
pip2 install git+https://github.com/agermanidis/autosub.git (after cleaning up .local)
pip3 install git+https://github.com/agermanidis/autosub.git (after cleaning up .local)

Tried all combinations. First it didn't work. Then one day later it worked. Then next day stopped working, again.
Tried the pip install and/or clone and/or .zip. Also tried other repo's.
Under Ubuntu for Windows 10 still working, but a copy from there is not working under real Linux.
Please help.
Is it obstructed? Like (lots) of other stuff? (40 years of experience on things like this. Almost never something works good.)
