Trouble upgrading to 25.0.0 from 24.0.4

[KptnKMan]

Hi @iamklaus I'm using this docker for some time, and I have seen that a new version was released for 25.0.0, and I'm trying to upgrade to the latest, but I'm having a lot of issues.

I'm hoping someone can help, or maybe there are others experiencing the same issue?

When I go to the URL "http://192.168.1.100:8098/updater/" (My local docker instance host address), I get this issue with the updater:

Also, I can access the instances console, but I am having trouble ininitalising a manual update. When I try to run (As root user):

root@b9d54993f69c:~# sudo -u www-data php /var/www/html/occ upgrade
Nextcloud is already latest version

I've been trying more things for some time now, but I'm kind of stuck.

Can anyone help?
