With this I was finally able to fix my problem too. Both times the manage.py script went through, but I had to make some aditional changes: as I've replaced the mailman3-web systemd unit with an ini for the uwsgi emperor, which runs mailman3-web with list:list, I've owned the mailman-web.py in /etc by list:www-data. Afterwards the website would load again, but only work partially. It turns out it coudln't find "/var/lib/mailman3/web/static/postorius/libs/bootstrap/js/bootstrap.min.js.map". I fixed it by removing the postorius directory (better: rename it) and create a symbolic link to /usr/share/python3-django-postorius/static/postorius (and of course changing ownership). Now it works, case closed from my side.

I only had to: - install sudo (my debian installation was a minimal netinstall, without that package) - chown -R www-data /usr/share/mailman3-web I had also to add a mail address to my admin profile and set it to preferred (I only had root@mydomain as address). Thnakyou!
