Linux

Debian / Ubuntu

Note: Raspberry Pi OS and Raspbian are both flavors of Debian

Easy Install

For the Debian / Ubuntu / Raspbian beginners there isn't an Apt Repository or Deb package.

If you want an easy life, follow this community provided and maintained Easy Install script for a base Debian (Raspbian / Raspberry Pi OS) / Ubuntu install.

For the official installation instructions that are 'Hands on' follow the Debian / Ubuntu Hands on Install steps further below.

Please see the *Arr Community Installation Script

Radarr uses a bundled version of ffprobe for media file analysis and does not require ffprobe or ffmpeg to be installed on the system. If Radarr says ffprobe is not found this can typically be fixed with a reinstall.

Debian / Ubuntu Hands on Install

It is assumed you have a basic knowledge of linux or the ability to google / learn as necessary. Otherwise it is suggested to use an OS you know and understand

You'll need to install the binaries using the below commands.

The steps below will download the stable version (master release branch) Radarr and install it into /opt
Radarr will run under the user radarr and group media; media is the commonly suggested group to run the *Arrs, download clients, and media server under.
Radarr's configuration files will be stored in /var/lib/radarr

  • Ensure you have the required prerequisite packages:
sudo apt install curl sqlite3

Installation Prerequisites
The below instructions are based on the following prerequisites. Change the instructions as needed to suit your specific needs if necessary.
* The user radarr is created
* The user radarr is part of the group media
* Your download clients and media server run as and are a part of the group media
* Your paths used by your download clients and media server are accessible (read/write) to the group media
* You created the directory /var/lib/radarr and ensured the user radarr has read/write permissions for it for it
* Previous/existing installations were using the master release branch noted on the FAQ or you update master in the download URL

By continuing below, you acknowledge that you have read and met the above requirements.

  • Download the correct binaries for your architecture.
    • You can determine your architecture with dpkg --print-architecture
      • AMD64 use arch=x64
      • ARM, armf, and armh use arch=arm
      • ARM64 use arch=arm64
wget --content-disposition 'http://radarr.servarr.com/v1/update/master/updatefile?os=linux&runtime=netcore&arch=x64'
  • Uncompress the files:
tar -xvzf Radarr*.linux*.tar.gz
  • Move the files to /opt/
sudo mv Radarr /opt/

Note: This assumes you will run as the user radarr and group media. You may change this to fit your usecase. It's important to choose these correctly to avoid permission issues with your media files. We suggest you keep at least the group name identical between your download client(s) and Radarr.

  • Ensure ownership of the binary directory.
sudo chown radarr:radarr -R /opt/Radarr
  • Configure systemd so Radarr can autostart at boot.

The below systemd creation script will use a data directory of /var/lib/radarr. Ensure it exists or modify it as needed. For the default data directory of /home/$USER/.config/Radarr simply remove the -data argument. Note: that $USER is the User Radarr runs as and is defined below.

  • Reload systemd:
sudo systemctl -q daemon-reload
  • Enable the Radarr service:
sudo systemctl enable --now -q radarr
  • (Optional) Remove the tarball:
rm Radarr*.linux*.tar.gz

Radarr uses a bundled version of ffprobe for media file analysis and does not require ffprobe or ffmpeg to be installed on the system. If Radarr says Ffprobe is not found this can typically be fixed with a reinstall.

If Radarr did not appear to start, then check the status of the service:

sudo journalctl --since today -u radarr
