Radarr is an independent fork of Sonarr reworked for automatically downloading movies via Usenet and BitTorrent.

Initial Setup

Installing Radarr is easy. Simply issue the following command:

sudo box install radarr

This command will configure radarr for your user.

How to Access

After Radarr has been installed, it will be available for access at https://<hostname.ltd>/radarr.

Service Management

The Radarr service is managed by systemd and has been configured for single user usage. You can find the service file here:

sudo systemctl start radarr


Out of the box, Radarr comes with very little configuration. Following are some basic tasks to help get your client up and running:

Add a new show (and your first root directory)

  1. At the top, click series.
  2. Click the button + Add Movie
  3. Type the name of the show you want to add
  4. Under Path, choose Add a new path. Enter the path for the folder you wish to add your Sonarr shows to and click the green check mark to add the directory.
  • e.g. /home/<username>/media/Movies
  1. Change the other settings to your own needs
  2. Click the green + to add the show.

Connect download clients

To add a download client, go to Settings > Download Client. Make sure Advanced Settings are shown and click Add Client.

Name: rTorrent
rTorrent host:
URL Path: /rutorrent/plugins/httprpc/action.php
Username: <your username>
Password: <your password>
Add label to torrent: TV (or anything else you desire)
Optional - Downloaded files location: <custom directory>

Add an indexer with Jackett

Radarr only supports a few trackers out of the box, but the indexers can be expanded by using the application Jackett. To add an indexer with Jackett, use the following steps.


By default, when receiving the torznab feed from Jackett, it will need to be modified to be connected with the application. The default link looks like:


We need to edit this link to remove https and add the port number. Thus, if your port number was 12345, your edited URL would look like this:

  1. Go to Settings > Indexers and click + to add a new indexer.
  2. Under Torrent choose Torznab
  3. Use the settings:
Name: <tracker name>
URL: <click copy torznab feed in jackett and modify as per above>
API: <copy and paste from jackett UI>
  1. Click Test. If all is good, click Save.

Other tasks

You may wish to further alter your setup by setting quality profiles or setting up post-processing so that media is automatically transferred to your Radarr library when your torrents are completed. If you need further help, you can refer to the Radarr Wiki.

  • Upgrade mono-based v0.2 to mono-based v3
    1. Trigger a backup manually by going to System -> Backup and presds the "Backup" Button. Wait until the process has finished.
    2. Change the Release branch by going to Settings -> General -> Updates (needs Advanced settings shown), set the Branch value to master and then press the Save button
    3. Go to System -> Updates and install the latest update which should be version 3.x+
