I am dist-updating my Debian system. I get a failure for the installation
of Mailman3-web

root at tagol~# dpkg --configure mailman3-web
Setting up mailman3-web (0+20240312-1) ...
dpkg: error processing package mailman3-web (--configure):
 installed mailman3-web package post-installation script subprocess returned error exit status 20
Errors were encountered while processing:

  I tried replacing the set -e with set -x in

/var/lib/dpkg/info# e mailman3-web.postinst

  Then I get

root at tagol/var/lib/dpkg/info# dpkg --configure mailman3-web

  Running

  yields nothing

  Same thing.

root at tagol~# systemctl restart mailman3-web.service
root at tagol~#

  The web interface page loads

https://folks.email/mailman3/postorius/lists/bibnez.folks.email/

  but when I go to sign-in I get

Internal Server Error: /mailman3/accounts/login/

OfflineGenerationError at /accounts/login/
You have offline compression enabled but key
+"5dc9242d199e3c2224564016de526a9d8e46b5d332709d1fde99964e8821452c" is missing from offline
+manifest. You may need to run "python manage.py compress". Here is the original content:

  I go ahead and run

root at tagol/usr/share/mailman3-web# ./manage.py compress
Compressing... Error parsing template socialaccount/signup.html: socialaccount/base.html

  It turns out this issue was discussed on the mailing list

https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/MGY6JA6O7BWGR2KNKD3PQTMW7ZY7NHS3/

  I tried to downgrade

root at tagol~# dpkg -i mailman3-web_0+20200530-2.1_all.deb
dpkg: warning: downgrading mailman3-web from 0+20240312-1 to 0+20200530-2.1

  So I upgrade again

root at tagol/usr/share/mailman3-web# apt upgrade
The following packages were automatically installed and are no longer required:
  libabsl20220623 libaio1 linux-image-6.6.15-amd64 python3-editables python3-pyrsistent
Use 'apt autoremove' to remove them.

  Removing these two lines

root at tagol/etc/mailman3# diff mailman-web.py mailman-web.py~
53,54c53,54
<     'allauth.account',
<     'allauth.socialaccount'
---
>     #'allauth.account',
>     # 'allauth.socialaccount',

 restarting mailman3-web, and then adding them back again, and then
 restarting mailman3-web, magically seems to get the web interface to
 work. But the error on install still persists.

root at tagol/etc/mailman3# apt upgrade

  Let me know if there is anything I can do to help.
