The issue you are facing:
After upgrading from Nextcloud 24.0.8 the

Is this the first time you’ve seen this error? (Y/N): no, I already tested a los

Steps to replicate it:

  1. Install Nextcloud 24.0.8, configure custom background picture
  2. Update to Nextcloud 25
  3. Logout and try to Login again, you won’t see your background picture anymore, just a blank color

Strange thing:
Directly after the update, when still being logged in, the background image is there. But once being logged out or using another browser…it’s gone. I assume it’s a caching problem here but I still wanted to mention it.

Problem:
We’re hosting a few nextclouds for our customers and update them regulary. Some of the customer use custom designs like favicon, background image etc.
After updating our own nextcloud I realized, that the background image was gone.

Testing it with a testing instance I found out, that the images were previously stored at

data/appdata_xxxxx/theming/images/

When upgrading nextcloud the folder images gets deleted.

With nextcloud 25 the path changes to

data/appdata_oc3ofb7zlt0w/theming/global

There i no “images” folder. If I set a new background picture the folder appears and contains the picture.

I tried to save and copy the files form Nextcloud 24 there but it didn’t help.

Why can the custom config not be transfered to Nextcloud 25? This has a huge impact since the customers would have to reconfigure everything.

Can someone tell me what we can do to avoid the reconfiguration?

Thanks in advance!

Same issue here!
Any remedy as of now?

Just updated to 25.0.3 (stable channel) and lost my favicon and background image too.

I can’t find the background image from the backup either (nextcloud/data/updater-xxxxxxxxx/backups/nextcloud-25.0.2.3-1674003779/…)

Anyone knows where I could find it? I do have a cold backup (ZFS disk snapshot) from a previous instance, but that’ll take a while to find for sure…

Any input from Nextcloud’s team?

Same issue! And it wont update anymore when i upload a new one!
