[MM3-users] Re: mailman3 on new Debian 12 installation, got ssl apache working on all URLs except /mailman3

My /etc/mailman3/urls.py is empty.

Should I, like it indicates in https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/...

cp /opt/mailman/venv/lib/python3.11/site-packages/mailman_web/urls.py /etc/mailman3/urls.py chown mailman:mailman /etc/mailman3/urls.py and add to /etc/mailman3/settings.py

ROOT_URLCONF = 'urls'

After completing above, https://systemdatabase.ca/mailman3 still gives Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
