[MM3-users] Upgrade Mailmam Core from

Hello,

I have newly set up Mailman 3 on Ubuntu 20.04. Sending and receiving mails between list members does work, but I am currently experiencing two issues:

1. a lists non-members who send mails to the list don't get notified about the message being held for moderation. Moderation itself doesn't seem to work. The moderation list is always empty.
2. Archiving is activated within list settings, but there isn't any archive created.

I found this thread, where the first of these issues is also described: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/K...

Here there is an incompatibility between Mailmain 3 and Python depicted, which also seems to affect me. I am running Mailman 3.2.2 on Python 3 .8.10.

So I need to either upgrade Mailman Core or downgrade Python. I already did

apt-get upgrade apt-get update Unfortunately this didn't upgrade Mailman Core's version.

Which steps do I have to undertake to upgrade Mailman Core?

Regards, Sascha.
