I think I have it now in part. The symlink did not work (odd I did not get an error) but is correct now:
<venv> $ ls -l /opt/mailman/var/etc/mailman.cfg lrwxrwxrwx 1 mailman mailman 25 Nov 9 12:01 /opt/mailman/var/etc/mailman.cfg -> /etc/mailman3/mailman.cfg
I can now see the list. I can't find the URL for members so I'm not sure if this really worked.
<venv> $ mailman import21 lllllllllll@ddddddddd.net /tmp/config.pck Importing members [####################################] 100%uuuuuuu@aol.com is banned and not imported with role MemberRole.member
Importing owners [####################################] 100%oooo@ddddddddd.net is already imported with role MemberRole.owner
Importing moderators [####################################] 100% Importing defers [####################################] 100% Importing holds [####################################] 100% Importing rejects [####################################] 100% Importing discards [####################################] 100%
It seems the archives were imported but when I go to that page there are no entries:
