Decide on Python version.
Right now we advise to use either python 3.6 or python 3.7, but SciLab also works with python 3.10.
Ubuntu 20.04 comes with python 3.8 and Ubuntu 22.04 (releases on 22.04.2022) will come with python 3.10.
It would be good to decide which versions of python we'd like to support/test.
