Permission denied if not owner

[AnonymousX86]

Describe the bug
Bazarr can't save files if user is not owner of desired directory or directory is not protected (chmod o=rwx).

To Reproduce

1. Create user bazarr with group.
2. Create user radarr with group.
3. Add user bazarr to group radarr.
4. Change /movies directory ownership to radarr:radarr.
5. Apply permissions lesser than o=rwx, e.g. 0775.
6. Run Bazarr with PUID and PGID of bazarr.
7. Bazarr can't save subtitles due to "Errno 13: permission denied".

Expected behavior
Bazarr should save subtitles, as it has sufficient permission to directory (g=rwx).

Additional context
Example:

$ cd /movies
$ ls -l | grep Dune

$ ls -l Dune
total 2539684
-rwxrwxr-x 1 radarr radarr 2599600403 Jun  1 01:28 'Dune.mp4'

Docker logs:

Issue does not occur when applying o=rwx permissions. Subtitles are being saved with bazarr:bazarr ownership with 644 permissions.

$ ls -la
drwxrwxrwx 1 sonarr sonarr     12288 Jul 15 21:55 .

I’m dealing with the same issue

Could you please enable debug log, reproduce the issue and provide the log file?

No news, good news!

I was having the same issue, both directories and files are under owner sonarr, and group media, where the users sonarr and bazarr are under this group.

The issue arrived because Sonarr created the directories with write permissions only to the owner, so I fixed it by going into Sonarr media management settings. Enabling the advanced options will show the file permissions options, changing the chmod folder option to 775 (write permissions to owner and group, read permissions to all) fixed the issue.

This only changes for future content, to fix the current directories you will need to run chmod g+w <media directory> to fix it.

This was the error I was seeing the logs of bazarr before applying the fix:

I'm using bazarr v1.5.6, running as a systemd service under nixos, using the module provided by nixpkgs.
