When I go Access Rights Management / Shared Folders / Add, I populate the name, select a device, allow the default path and permissions, but when I hit Save, I get "Failed to set file group to 'users' for '/srv/dev-disk-by-uuid-4C9A-901D/movies/"
This is the correct UUID for the disk. (Although, it looks a little short!)
It's a USB drive. I don't know if that's significant.
There is a "users" group. (My user is a member of it.)
If I now hit "Cancel" the directory has been created (I can see it on the console) and the share appears in the GUI.
Looking for clues as to what might be causing the error, please?
