Nextcloud Server version: 25.0.0
Nextcloud Desktop Version: 3.6.1
Server Operating system and version: Ubuntu 22.04 server
Desktop Operating system and version: Ubuntu 22.04 desktop
Apache or nginx version: Apache - docker compose
PHP version: docker compose

The issue you are facing:
I have folder with about 4Gbs of photos. 3 of them were not sync’ed. I moved them out of their folder into a different folder and then they synced. If I try to move them back to the original folder they jump back out the the second folder I put them in (I can’t put them into the original folder).

Is this the first time you’ve seen this error? : Y

Steps to replicate it:

  1. copied a big folder to nextcloud last night.
  2. checked today and noticed 3 files hadn’t sync’ed
  3. move files to new folder, then try to move them back to original folder.

I had recently upgraded from version 24 to 25 and thought maybe that was the problem. I just tried to downgrade but the container wont start.

Can't start Nextcloud because the version of the data (25.0.0.18) is higher than the docker image version (24.0.6.1) and downgrading is not supported. Are you sure you have pulled the newest image version?

Ouch!
