Permission problem after moving data folder

ℹ️ Support
1

Hi all,
i’m new to nextcloud and i’m not able to resolve this problem.
I installed nextcloud on a new vm running ubuntu server using the standard installation script.
After that i moved the data folder using the solution1 as explained in this topic: HowTo: Change / Move data directory after installation

Now i’m able to access the files in the new directory but i can’t delete or add new files.

the new data path is in /mnt/nextcloud and it is a samba share auto mounted at the server startp with cifs utils.

Also the command
sudo -u www-data php -f /var/www/html/nextcloud/console.php files:scan --all
report:

Permissions can usually be fixed by giving the web server write access to the root directory. See https://docs.nextcloud.com/server/24/go.php?to=admin-dir_permissions.

An unhandled exception has been thrown:
Exception: Environment not properly prepared. in /var/www/nextcloud/lib/private/Console/Application.php:164

Did you try visiting this link it pointed you to?

https://docs.nextcloud.com/server/24/go.php?to=admin-dir_permissions

You can also verify your permissions and ownership of the directories with ls -la
And change those permissions with chown and such

The link unfortunatly is not giving any useful information.

LS -LA Results:

Actually it is useful. Nextcloud normally is www-data and not root as far as I know for user or group permissions. :person_shrugging:

Your new data folder needs to be www-data as opposed to root

Was the problem resolved? Wenn yes, how?

6

For the data directory try to do

sudo chmod 770 /mnt/nextcloud

If that doesn’t work, try also

chown -R www-data:www-data /mnt/nextcloud

(Change /mnt/nextcloud to your path)

This topic has come up a zillion times here in the forum and was even answered in this thread.

The Nextcloud folder and data folder should be owned by the web server user. On Debian/Ubuntu based distributions this is usually the user www-data. Further it is recommended to set the permissions for folders to 750 and for files to 640.

chown -R www-data:www-data /path/to/nextcloud
find /path/to/nextcloud/ -type d -exec chmod 750 {} \;
find /path/to/nextcloud/ -type f -exec chmod 640 {} \;

Thanks for information
I have the same problem - but on a Proxmox-container.
Is the soluten the same for Proxmox?
I think, it’s different to use the accounts - in Proxmox uid ?

I don’t use LXC myself but I’d say yes.

I don’t think so, because Nextcloud and the web server ar not aware they are running in a container, so the Nextcloud folders and files, including the data folder and its contents, need to be owned by www-data, regardless from where and how the storage is mounted.
