Questions[mailman](ubuntu)

need some help please.

I installed mailman3 and mailman3-web and all the related stuff using apt install .. . The mailman backend seems to work properly. Trying to access the web frontent "postorius" just gives me the starting page showing the postorius logo and some Links to "Lists", "Achives" and so on and an error message in a red box: "This page either doesn't exist, or it moved somewhere else."

my url is : http://my.host/mailman3/postorius/lists/

Looking at the links in the page head leads me to a slightly different url .. http://my.host/mailman/postorius/lists/ . ( missing '3' with mailman) Clicking these links leads to an 404 error.

Why is postorius changing the root directory from mailman3 to mailman ? Of course, these links are not reachable.

I thaugt, this path name was somwhere linked hardcoded. So I changed the apache config to use the root path /mailman/ instead of /mailman3/ . But what happens is: the path given by postorius is now /mailma/.. missing "n" at the end.

How can I fix this ? I don't have any knowledge about programming in python, so I can't debug it myself ..

thanks for any suggestion

Ubuntu 20.04.3
mailman 3.3.2

I have an Ubuntu 18.04 LTS server that at one point in time was set up (not by me) to run GNU mailman, using Postfix as the MTA.

I no longer run any mailinglists on this server, and have ‐ to the best of my ability ‐ tried to remove and purge Gnu mailman from the server by running these commands:

sudo apt remove mailman
sudo apt autoremove mailman
sudo apt purge mailman
sudo apt autoremove --purge mailman

This removes mailman and some (most?) configuration and data files, but when I look in the Postfix log (/var/log/mail.log), I get these about every five minutes:

[…]: error: open database /var/lib/mailman/data/aliases.db: No such file or directory
[…]: warning: hash:/var/lib/mailman/data/aliases is unavailable. open database /var/lib/mailman/data/aliases.db: No such file or directory
[…]: warning: hash:/var/lib/mailman/data/aliases: lookup of 'root' failed

I understand why I get them, since purging GNU mailman deleted all those files.

I am pretty sure that the program that requests these files is Postfix, as running:

sudo service postfix status

… produces the same three lines of errors and warnings. However, I am unable to figure out what it is that makes Postfix want to open these files.

Restarting postfix:

sudo systemctl restart postfix

… cleans out the errors, but only temporary. After about five minutes, they are back when I check status.

The question is this: How to I get rid of these errors and warnings (without reinstalling the no longer needed application)?

I've been fighting with this one for a while. I've followed all the tutorials I can find and apache2 just doesn't display any of my mailman pages. I'm running ubuntu 16.04.1 LTS

What's the best way to further troubleshoot this? What other information is needed? If this isn't the correct place, where should I go for help?

Thanks!!!
