Folder Ownership Changing, and I'm Losing Permissions

[soodoenim]

I am on Jellyfin Version 10.8.13 running on Ubuntu 22.04.4

I have a 4TB HD on a Lenovo ThinkCentre running as a NAS, and another 4TB HD on the same ThinkCentre not running as a NAS. The issue I'm encountering relates to permissions on the sub folders on both drives. Most of the folders are showing up as owned by me, while many are showing up as owned by an Jellyfin. The folders owned by Jellyfin only give me access permissions, and I need permission to create and delete files on those folders. How do I go about changing the default permissions on the folders that Jellyfin is creating so that I can create and delete files on them?

You would use the "chown" and "chmod" commands to modify permissions. But Jellyfin will continue to make new folders with jellyfin:jellyfin ownership.

You could add your user to the jellyfin group.
