Install, step 5 issues

[ahalota]

I'm following the instructions here: https://actinia.mundialis.de/tutorial/installation.html

    cd /tmp

    virtualenv -p python2.7 grass_venv
    source grass_venv/bin/activate
    cd actinia_core
    pip install -r requirements-grass-gis.txt

As with step 4, I assume that we are meant to cd $HOME/actinia/workspace/tmp and not just /tmp.
The instructions say we need to have a python3 env for grass ,but the code sample shows 2.7. That should be 3?

There is no file "requirements-grass-gis.txt" in the actinia_core folder. I have one called "requirements.txt" and requirements_ubuntu19.txt".

Both seem to have notes about different versions, possible changes, etc. I will continue with "requirements_ubuntu19.txt" (I'm running Mint 20) and see how it goes.

Went ok except for this error:
ERROR: sphinx 3.5.4 has requirement docutils<0.17,>=0.12, but you'll have docutils 0.17 which is incompatible.
Since that's just for documentation, I'll ignore it for now.
