Nextcloud permissions error ruining my experience

[Monkeyfume]

I’m stuck, and no resource I can find online has the solution I need.

I installed Nextcloud through Snap on Ubuntu 16.04, for convenience. It worked perfectly, but my SSD doesn’t have the space I need, and I had to redirect Nextcloud’s data directory to /media/raid750/nextcloud/data. /media/raid750 is where my 750GB RAID1 array is mounted. Yes, Nextcloud has access to removable devices in the /media/ directory. The RAID array is in the Ext4 file system; the array was initially formatted in NTFS, but I reformatted to Ext4 because I thought that was the reason behind my following problem (it apparently wasn’t).

When I try to connect to Nextcloud from another computer, I get the error:

Your data directory is readable by other users
Please change the permissions to 0770 so that the directory cannot be listed by other users.

I searched far and wide for a remedy to this issue. One of the suggestions was to enter the command ‘sudo chmod 0770 /media/raid750/nextcloud’. I did this, and nothing changed: I still got the same error, even after restarting Nextcloud.

Another suggestion was to enter ‘sudo chown www-data:www-data /media/raid750/nextcloud’. Instead of solving the problem, that command resulted in the following errors:

Your data directory is invalid
Ensure there is a file called “.ocdata” in the root of the data directory.
Cannot create “data” directory
_This can usually be fixed by giving the webserver write access to the root directory. See Introduction — Nextcloud 12 Server Administration Manual 12 documentation

This feels like a step farther away from the problem. Setting chown back to root for my directory takes me back to the first problem, changing the permissions to 0770. I really don’t know what to do. Do I need to modify something in /etc/fstab, even though my array is Ext4? Please help. Thank you!

Did you try this?

Also, if that doesn’t work, the following should help:

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

In both examples, remember to change any references to nextcloud to the directory that you want to change the permissions on.

Thank you !

This worked beautifully.
