Radarr, Sonarr, Lidarr & Jackett¶

These .NET-based packages provide media management capabilities.

Architecture Support¶

The newer .NET packages provide many benefits, but unfortunately not all architectures are supported. If you are unsure what architecture your NAS is running, check the Architecture per Synology model page.

Known Issues¶

Unable to Update Radarr¶

It's a known issue when running multiple *arr applications. Stopping Sonarr then updating Radarr resolves the issue.

Related: #4679, #4621

rtd1296 (armv8) Devices and Mono¶

Sonarr v4/Radarr/Lidarr/Jackett .NET core versions should work correctly.

Sonarr v3 is end of life and not supported by the Sonarr Team.

Radarr on DS715 (alpine) - "Killed" or "terminated with status 1"¶

This CPU architecture is not supported at the moment. See #4546 and #4793.

Downgrade Mono Without Uninstalling (Advanced)¶

Instead of uninstalling the higher version, you can fake a lower version number by modifying the INFO file:

SSH into the diskstation
sudo vi /var/packages/mono/INFO
Modify version from "5.20.1.34" to "5.8.0.108" and save
Then it will display as 5.8.0.108 in DSM package center and you can manually downgrade

Alternative Options¶

Docker (aarch64)¶

If your NAS supports Docker, you can use Docker images instead:
