mailman won't work after install

[Ternoc]

After initial install, mailman won't work and show this error page

Yunohost version : 4.3.3

When accessing to services pannel in Yunohost, it shows that the mailman status is X auto restart.

There is the logs :

Same, seems to be since either commit 289bf408d57bf564d6cdaa9324b4f0152eee379a or Yunohost 4.3 release according to CI : (last successful run without this error) https://ci-apps.yunohost.org/ci/job/3804

After manually sudo /usr/lib/mailman/bin/mailmanctl -s start (command which is done by the service), /var/log/mailman/error shows

Dec 09 13:34:06 2021 mailmanctl(6153): Site list is missing: mailman
Dec 09 13:34:06 2021 (6153) Site list is missing: mailman

Sooo... Here's my log gathering plan :

1. rm /var/log/mailman
2. Install Yunohost app
3. Wait 5 mins
4. Upload content of /var/log/error and /var/log/qrunner

Install logs : https://paste.yunohost.org/raw/mirojuxibu /var/log/error : https://paste.yunohost.org/raw/okibetodef /var/log/qrunner : https://paste.yunohost.org/raw/faqiyepevo

Nothing strange in install logs, and mailman list is correctly created :

admin@vivaldi:~$ sudo /usr/lib/mailman/bin/list_lists 
1 matching mailing lists found:
    Mailman - [no description available]
admin@vivaldi:~$ sudo /usr/lib/mailman/bin/list_admins

Well, seems it's not related to 4.3 release as I thought, but may well be related to a commit, because when package_check checks "upgrading from old commit" it works at least for a second... So, it broke somewhere between commit 289bf408d57bf564d6cdaa9324b4f0152eee379a and commit 74754abc96057eec8f9a4c8902ad43299950c8b3, let's figure out where exactly :)
