Mediawiki error 500

Support

Problem Description
Installed Mediawiki on a fresh install of FBx, up to date bullseye. When changing the admin password I got error 500.
As I had a backup, I ignored this error and did a restore from buster. That however gave error “Fatal exception of type “Wikimedia\Rdbms\DBQueryError””.

Information
Error: “No such user: admin”

I would like to purge Mediawiki and try again. When will this function be integrated in Plinth, I think there was a discussion about this?
What happens, if I do an apt reinstall of Mediawiki? Will this help and keep the integrity of FBx?

I also followed the instructions in “MediaWiki content gone, "History" shows DBQueryError - #2 by njoseph” and I could change the admin password (previously got error “no such user” or so).
I will NOT run restore but will copy content again manually.
So the issue resolved - but not understood.

EDIT: funny, my wiki content is already back, I just have to upload the images.

I got a 500 error while attempting to update the admin password (on bullseye), but for a different reason: “Passwords must be at least 10 characters. The password entered is in a list of very commonly used passwords. Please choose a more unique password”. The underlying problem seems to be that Mediawiki raises an exception when the password update fails and the exception isn’t getting caught and handled (presumably to display the message to the user). However, I also see Issue 1260, which suggests that FreedomBox admins should automatically be made MediaWiki admins, which would make the Mediawiki config admin password update function unnecessary (but not necessarily eliminate the need to catch password-related Mediawiki exceptions, depending on how Mediawiki admins are sync’d with Freedombox admins).
