What steps did I miss? If you are setting up according to the virtual environment instructions, Mailman shouldn't be looking for anything in /var that you didn't explicitly configure to be there. With the venv active, try running just "mailman info". If that succeeds and reports something other than /etc/mailman3/mailman.cfg, then check the file it reports for "layout" and "var_dir" settings, and remove the var_dir hierachy because it's just confusing. Then run mailman -C /etc/mailman3/mailman.cfg info If that succeeds, try starting Mailman with mailman -f -C /etc/mailman3/mailman.cfg start The "-f" is short for "--force" and it just cleans up any stale lock files that might prevent Mailman from starting. (We now recommend using it in the init script or systemd unit file ExecStart command.) If either of those fails, or Mailman starts but "doesn't work", look in the logs (systemctl status, journalctl -eu, and $var_dir/logs/mailman.log for error messages, and send those along with /etc/mailman3/mailman.cfg to us. In the case of "doesn't work", tell us what you mean by "doesn't work": Mailman doesn't accept mail, Mailman crashes, Mailman doesn't send mail, etc.
Hi Steve,I found the docs for MySQL and I THINK I have it working. However this line from the status is concerning:
