How do I modify permissions so Jellyfin can delete files without messing up Sonarr?

[Robin Ogilvie]

I'm using Sonarr and <something we don't mention here> to find and download my files.  Currently I have Jellyfin referencing the Library for my shows at "/NAS/sonarr"

I'm not well versed in linux permissions at all, but when I run

Code:

ls -la /NAS/sonarr

I get:

Code:

drwxr-xr-x 4 sonarr sonarr    6 Sep 17 02:53  .
drwxr-xr-x 7 root  root      9 Sep  4 13:55  ..
drwxrwxr-x 3 sonarr sonarr    5 Sep 17 02:42 'Big Brother (US)'
drwxrwxr-x 3 sonarr sonarr    5 Sep 17 02:40 'The Amazing Race Canada'

When I try to delete files via Jellyfin it says "There was an error deleting the item from the server. Please check that Jellyfin has write access to the media folder and try again."  I presume this is because Jellyfin is using a different user than "sonarr".

How can I go about modifying permissions so that both Sonarr and Jellyfin both have privileges to read, write, modify, and delete these files?

Without giving wide open permissions, you could add jellyfin to the sonarr group.

sudo usermod -a -G sonarr jellyfin
