[MM3-users] Unable to get mailman3 working on Ubuntu 20.04 LTS

26 Oct 2021


      Hi all,
after upgrading an older server to Ubuntu 20.04, I tried to first upgrade my old mailman 2 installation to mailman 3. I've been on it for three weeks now, but unable to get anything working. I have long forgone the idea of upgrading and thus purged everything from mailman2 on my machine, and installed and removed mailman3 several times to no avail.
My most recent try (it is currently an empty mailman installation) was done by calling
apt install mailman3 mailman3-full mailman3-web
and saying "yes" to every question. I'm using Mariadb as the database, and two databases called mailman3 and mailman3web (plus two users with the same names) have been created. I have configured a virtual host for apache (see below) and changed the mailman.cfg and mailman-weg.cfg to match (also see below).
I have restarted both mailman3 and mailman3-web several times now, but when I try to access the site, I just get
| Something went wrong
| Mailman REST API not available. Please start Mailman core.
plus an e-mail with subject
| [Django] ERROR (EXTERNAL IP): Service Unavailable: /mailman3/postorius/lists/
I'm running
| GNU Mailman 3.3.3b1 (Tom Sawyer)
| Python 3.8.10 (default, Sep 28 2021, 16:10:42)
Can anybody tell me what is going on? Also, the confirmation e-mail I got for registering a user says "example.com" in its subject line, even though I replaced every mention in the config files below with my actual URL.
Any help is appreaciated, I can provide logs or other data on request.
Cheers,
michael
