Been struggling to get Nextcloud installed from the app interface. From the research I’ve done - it’s boiling down to an old install that has some lingering files/configs somewhere…but it’s gone beyond me… I’ve gone through the thread linked below which seems to be the same problem, but can’t deter…

I could make it work just changing permissions, the problem is the postgres that it fails when the directory exists under: /mnt/.ix-apps/app_mounts/nextcloud Since there is no way to delete the directory you need to change the appname otherwise it fails over and over if you select the same name to…

Try sudo umount -f nextcloud to force the command

truenas_admin@truenas[/mnt/.ix-apps/app_mounts]$ sudo unmount nextcloud [sudo] password for truenas_admin: sudo: unmount: command not found truenas_admin@truenas[/mnt/.ix-apps/app_mounts]$ sudo umount nextcloud umount: /mnt/.ix-apps/app_mounts/nextcloud: target is busy. truenas_admin@truenas[/m…

Looks like it is busy right off the reboot

For anyone in the future… I found the answer with help on discord. sudo zfs destroy -r poolname/ix-apps/app_mount/appyouwanttodelete Be careful as this could mess up your system if the app is still in use. This will remove the left over data in .ix-apps.

Hey, I stumbled across the same problem. I deleted the pool as @vick-vinegar mentioned with sudo zfs destroy -r poolname/ix-apps/app_mount/appyouwanttodelete but the problem still exists. When I try to install nextcloud, I get the same error message. [EFAULT] Failed 'up' action for 'nextcloud' …

Got exactly same problem. I’m also waiting for someone to figure it out.

I haved seem problem with Nextcloud and Odoo. If i choose “ixVolume (Dataset created automatically by the system)”, it’s ok but not with HostPath. So it’s a problem with Postgres. OS Version:TrueNAS-SCALE-24.10-RC.2

I hope you all can find a solution. What I’ve found is that it’s really very very difficult to nail down “the” solution to a specific problem by means of the forums. Everyone’s installation is different and without sharing your specific use case, setup, and contributing setups (i.e. All the other a…

Try setting ACL permissions for the postgres volumes so the user:group 999:999 has read and write access

Hi, I had a similar error when trying to modify the installed nextcloud app from using the default “ixVolume (Dataset created automatically by the system)” directories to a custom “Host Path” directory. error: chmod: changing permissions of ‘/var/lib/postgresql/data’: Operation not permitted I d…
