Internal Server Error: /mailman3/postorius/lists/.../held_messages - humanize: where to put?
Hi,
I have setup in Debian Trixie mailman3-full and came that far, that I have created a mailing list. I can sent emails to the members.
However when I send from an email which is non-member the message is held. If I want to accept this message as list admin, I get:
An error occurred while processing your request.
And I get an email:
`Internal Server Error: /mailman3/postorius/.../held_messages

humanize is in the INSTALLED_APPS section in /usr/share/mailman3-web/settings.py. In this file I I configured Django. However it's not in the Python path as written in the error email above. So maybe I have to find a different settings file.
Can anyone advise me where I can find the error I have in my configuration?
Thanks in advance.

Your primary support resource for the Debian package is Debian. See https://wiki.list.org/x/12812344

You need to add 'django.contrib.humanize' to the INSTALLED_APPS list in settings.py. If you Debian packages don't do this, it should definitely be reported to Debian.

That's right.
You need to add 'django.contrib.humanize' to the INSTALLED_APPS list in settings.py. If you Debian packages don't do this, it should definitely be reported to Debian.
In /usr/share/mailman3-web/settings.py there is:
INSTALLED_APPS = (
...
'django.contrib.humanize',
...)
And POSTORIUS_TEMPLATE_BASE_URL = 'http://localhost:8001' I think this has also something to do with it. But looks correct for me.

But maybe the path

Right, that's why Python is looking for it. Since it's not being found, I guess there's a version skew between Mailman and django.contrib. The first thing to do is to make sure all your packages are up to date. Check if the django package (or maybe django-contrib if it's a separate package) is pinned to a particular old version, and consider unpinning and upgrading it. If they are up to date, and you're skilled with Debian, you may consider adding more recent package sources (testing or experimental) and install Django from those sources.
If that's not appealing I would strongly discourage trying to add the humanize package from Django upstream. That is a real can of worms. If you wish to continue using the Debian packages, you will need to get help from the Debian maintainers. I wouldn't be surprised if they already are planning to do something about this issue.
The alternative would be to uninstall the Debian package and install the most recent Mailman packages from PyPI in a Python virtual environment /opt. This probably requires installing the Debian python3-venv package. This is not terribly difficult, the instructions at docs.mailman3.org/en/latest are good, and you're welcome to ask for help on this list. We recommend this because you will get better support that way.
And POSTORIUS_TEMPLATE_BASE_URL = 'http://localhost:8001' I think this has also something to do with it.
That has nothing to do with it, they are quite unrelated.

Then I don't understand why you are getting the error. django.contrib.humanize is required because it is referenced by django-allauth in templates here https://codeberg.org/allauth/django-allauth/src/commit/5baeee79b2915dbb881d3... and here https://codeberg.org/allauth/django-allauth/src/commit/5baeee79b2915dbb881d3...
If django.contrib.humanize is loaded, those references should be satisfied.

Also using debian and had the same issue after upgrade to trixie.
I had to add 'django.contrib.humanize' to /etc/mailman3/mailman-web.py /usr/share/mailman3-web/settings.py seems to be only a fallback, settings are overwritten in /etc/mailman3/mailman-web.py, so adding it here (it is already there), may does not have any effect.

This made my setup work as well. Thank you so much for posting the solution! This saved lots of hours for me.
