Nextcloud Snap data permissions

ℹ️ Support 📦 Appliances (Docker, Snappy, VM, NCP, AIO)

Hi,

I’m running Nextcloud as a snap on Ubuntu 20.04

My data folder is a mounted NFS share on /media/nextcloud

It was accessible from other servers, and I made a mistake. I lost all permissions, but the data is still available.

I’ve tried to restore permissions but I’m doing something wrong, crearly. Automatic uploads fail with permission erros. And when I log in via web I get “internal server error”

I tried changing permissions to www-data:www-data, but nothing changed. Any help would be appreciated.

Thanks!

What was this mistake exactly?

Also, if you would, fill out the provided support template.

The data folder is a NFS share from my TrueNAS. I was changing permissions of some shares, and I made a mistake and changed the permissions of the dataset that contains the NFS share. Owner, group and access level changed to a Active Directory user and group.

I filled the support template, I’m starting to regret the decision of using a snap :stuck_out_tongue:

Nextcloud version: 24.0.3.2
Operating system and version: Ubuntu 20.04.2 LTS
Apache or nginx version: I don’t know how to get the version from the snap
PHP version:

The issue you are facing:

After loging in Nextcloud I get “Internal Server Error. The server was unable to complete your request. If this happens again, please send the technical details below to the server administrator. More details can be found in the server log.”

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

Can’t log in with Admin

Fixed it! :slight_smile:

Changed permissions to 0770 and root:root

It’s now working!
