just experienced a strange bug while I was updating my instance. I got the same message as @Crosant
Unfortunately his post never got an answer…
Here is basically the error in the updater:
When I hit the “Retry update”-Button I get the same message, nothing changes.
So I checked the updater.php, if I could find a mistake, because I did recently move my data-path into a new dir, cause of this
So I moved it back to the old place (and of course changed the config-value), but nothing changed and couldn’t find anything wrong in the updater.php.
Another strange behaviour is when I for example try to go back in browser:
The crossed-out path is just my domain, so the “/nextcloud/path”-part is missing.
