Description Sjoerd Mullender 2025-05-21 07:33:52 UTC 
After the hurdle of a missing nntplib (bug #2318976) the next hurdle is another Python 3.13 incompatibility.  It requires this patch:

--- /usr/lib/python3.13/site-packages/mailman/utilities/i18n.py-        2025-01-17 01:00:00.000000000 +0100

     # The non-language qualified $template_dir paths in search order.
-    templates_dir = str(resources.enter_context(
-        files('mailman').joinpath('templates')))
+    templates_dir = str(files('mailman').joinpath('templates'))
     paths = [templates_dir, os.path.join(config.TEMPLATE_DIR, 'site')]
     if mlist is not None:
         # Don't forget these are in REVERSE search order!

The incompatibility is that Python 3.13 dropped context support in pathlib.Path.

Reproducible: Always

*** This bug has been marked as a duplicate of bug 2318976 ***
Comment 2 Sjoerd Mullender 2025-11-12 16:12:26 UTC 
This is *not* a duplicate of bug 2318976.  2318976 is about nntplib which does no longer exist in Python 3.13.  This bug is about something entirely different: Python 3.13 dropped context support in pathlib.Path.
Comment 3 Sjoerd Mullender 2025-11-26 09:07:14 UTC 
Reopening this, since it is *not* a duplicate and the latest version of mailman3 (mailman3-3.3.10-1.fc42.noarch) suffers from this bug.
The patch still works.
