Import fails due to file permissions

Sonarr version (exact version): 3.0.5.1144
Mono version (if Sonarr is not running on Windows): 5.18.0.240
OS: Debian
Debug logs: https://1drv.ms/t/s!AqxCy5XCmw6hgQm-aSroCqnnBllU?e=ZrAS6b
Description of issue:

I have issues importing my downloaded TV Series from SABnzbd to my Jellyfin Directory…
In the logs it says some permissions are not set correctly but I tried everything I know to make it work. The Path does exist and the permissions are chmod 777, added sonarr to the jellyfin group and also changed the owner of the file to sonarr to see if that would work. I dont know what to do anymore.
Does somebody have an Idea or knows what information I can provide to solve this issue?

The file is recognized as downloaded but not importable:

Cheers Simon

that log file is not accessible.

what does an ls -lha show for the path that sab is reporting to sonarr?

what user/group is sab running as? what user/group is sonarr running as?

docker or not?

Why is that log file not accessible? I can open it in an inkognito window…

ls -lha shows the following:

sab is running as jellyfin in the group jellyfin
sonarr is running as sonarr and group sonarr
also groups jellyfin gives jellyfin : jellyfin sonarr

I am not using docker.

Thank you for your help!

From inside the The falcon... folder.

Is Sonarr part of the jellyfin group? If not a file owned by jellyfin:jellyfin won’t give access to sonarr:sonarr.

From inside the folder it’s the same:

yes:
groups sonarr gives sonarr : sonarr jellyfin

Fixed the issue by reinstalling sonarr with

sudo apt-get install --reinstall sonarr

and then creating the service file as user jellyfin so nothing can go wrong.
I didn’t have any NzbDrone.exe on my server so I just launched Sonarr.exe.
Thanks for your support.
