NextCloud does not start after a reboot

Ivan_SHatrykin · August 4, 2025, 2:47pm

The Ubuntu 22.04.5 LTS system.
The NextCloud is installed on snap. Ver 31.0.6.2 ???

during boot, it returns the error:
system_key.go:147: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: expected at least 3 fields, found 2

Everything used to work. NextCloud does not start after a reboot. The web interface is unavailable.

ivansh@nextcloud:~$ sudo snap start nextcloud

Hey @Ivan_SHatrykin welcome to the community and thanks for supporting the snap

looks like you’ve been bitten by a known bug mounting NFS in /etc/fstab. this seems to be an OS issue. see the solution below. your Nextcloud snap should be fine.

in my /etc/fstab was the “#” in the first line missing. So it wasn’t a comment. I added it an then it worked.
Had also no problem with boot process … so other process ignored this or handled it differently??? Don’t know … just a thought i had.
