Hi there,
I got a problem while updating my NextcloudVM (Hanssonit, running on Proxmox). The first steps are running smooth:
ncadmin@nextcloudvm:~$ sudo bash /var/scripts/update.sh

I get the following error:
So i looked up the path and indeed, there was no ‘.ocdata’:

As you can see, I created it, but that did not help. Would be to easy 
I guess I know where the problem comes from. On the initial installation I did choose a “local” disk as the “data-disk”. Afterwards i decided to use an NFS mount from a NAS system. I attached it and the NFS share is working fine and Nextcloud does not seem to have issues with it:
ncadmin@nextcloudvm:/mnt$ ls -lrt

I still have the /dev/sdb1 disc and attached it again on the VM:
ncadmin@nextcloudvm:~$ blkid

My wild guess: it still has some left-over configuration which is not needed anymore, but the update-script fails because of that.
Anyone can help me out with this?
Worst case: create new instance, this time correctly form the start, migrate data.
If you need any additional information, just let me know!
Best regards,
Bernd
P.S.: I changed some names and uuid’s. Nevermind.
