That looks OK. Are all the files readable by the mailman user? *Yes*
Is it possible that mailman-web was installed somewhere other than that virtual environment? *Not that I can find.*
Do I need to specify a path somewhere?
Not if you follow this procedure (note: assumes venv already exists and Mailman core was installed into the venv):
- cd /opt/mailman
- sudo su mailman # or somehow be the mailman user
- . venv/bin/activate
- python -m pip install mailmanweb # maybe that's mailman-web *Yes, it is mailman-web. In any case everything is satisfied.*
The point of activating the venv is that the installation process will ensure that the Python installation in the venv is referenced by all packages installed in the venv.
You should ensure that all of the executable paths in the systemd mailman (or mailman3) and mailman-web unit files are absolute paths pointing into the venv. *This looks right to me but nothing points to /opt/mailman/venv/lib. Should there be a lib_dir parameter set in mailman.cfg?

*I think the main thing is the MySQL stuff in settings.py:

Add lines:

At least so far.*
Thank you! That's useful.
