No extractable files found: Linux with all apps on one server/file system

Hi,
I am having an issue, can't figure out what I'm doing wrong :)

I am getting the error below:

Sep  7 13:31:16 debian-transmission unpackerr[4196]: 2020/09/07 13:31:16 [Sonarr] Updated (http://localhost:8989): 1 Items Queued

My settings for unpackerr sonarr/radarr are:

[[sonarr]]
   url = "http://localhost:8989"
   api_key = "myapikey"
   path = "/media/debian-transmission/Storage/Downloads/Completed"

[[radarr]]
  url = "http://localhost:7878"
  api_key = "myapikey"
  path = "/media/debian-transmission/Storage/Downloads/Completed"

Please advice as to why I am an idiot :)
Thanks

Is there a .rar file in /media/debian-transmission/Storage/Downloads/Completed/(edited out) ?

[SimonSR]

Yes

[davidnewhall]

Is this running in a jail? a chroot? a docker container?
What version is it? How did you install it?
Running on the same host as transmission and radarr/sonarr?

I can't really say what it is for sure. Maybe the answers to these questions will help, but I'm a bit stumped. If there's arar file in that folder, it should find it and extract it. Perhaps the app is running as a user without privileges to read that folder?

More:

ps aux | grep unpack < what user is it running as?

See if that user can read the folder:

sudo -u <username> ls "/media/debian-transmission/Storage/Downloads/Completed/(edited out)"

[SimonSR]

Installed this file: unpackerr_0.7.0-82_amd64.deb In ubuntu 20.04.
All apps running running on same host.

ps aux | grep unpack
nobody 5889 0.0 0.2 1000136 8624 ? Ssl 13:43 0:00 /usr/bin/unpackerr
debian-+ 6384 0.0 0.0 20200 728 pts/0 S+ 13:49 0:00 grep --color=auto unpack

[davidnewhall]

what user and group owns the files in /media/debian-transmission/Storage/Downloads/Completed/ ?

[SimonSR]

debian-transmission owns as both user and group

[davidnewhall]

Okay, try this.. edit /lib/systemd/system/unpacker.service and change the User= line to User=debian-transmission. You can also add Group=debian-transmission if you want. Then run:

sudo systemctl daemon-reload
sudo systemctl restart unpackerr

This will make the app run as thedebian-transmission user; giving it access to all those files. I'm not real sure if there's a better way to handle this at the moment, but hoping this works!

EDIT: I just combined/cleaned up comments for readability. Thank you for the report, and good luck!

[SimonSR]

It worked, thank you :) Looking forward to it

UPDATED: Unpackerr now uses a dedicated user in the systemd unit file and linux packages. The correct fix now days is to add the unpackerr user to the debian-transmission group and set the umask so the group can write.
