When python3 creates a venv, it adds python into it! This causes any upgrade recommendation to look like this: /devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4 . sphinx_2.4.4/bin/activate pip install -r ./Documentation/sphinx/requirements.txt With is wrong (and it may not work). So, when recomending an upgrade, exclude the venv dir from the search path, and get the system's python.
