Hi,
The settings module that's missing is your Django settings.py for HyperKitty and Postorius. Based on your command above, it should be found at /usr/share/mailman3-suite/settings.py
thanks for the hint, it seems there were some remains to be cleaned up after Debian changed from mailman3-suite to mailman3-web.
Best Regards Bjoern
