Install Radarr on Ubuntu

Before we begin Ubuntu Radarr installation, make sure you have a working Ubuntu or Ubuntu Server installation. If you need to learn how to install Ubuntu Server, follow our screenshot guide on how to Install Ubuntu Server 16.04 LTS Xenial Xerus.

1. Install Radarr dependencies

In order for our Ubuntu Radarr installation to run successful, we first need to install  the dependencies:

sudo apt update && sudo apt install libmono-cil-dev curl mediainfo -y

Looking for an automated solution? Try our AtoMiC ToolKit, which makes installation and management of Home Server software such as SickBeard, CouchPotato, Torrent clients, etc. easy.

2. Download Latest Radarr for Ubuntu

First, from the Radarr GitHub page right-click on the .tar.gz file for latest release and copy the link to the file. Alternatively, you can note down the full download URL.

Next, open Terminal in Ubuntu and download the latest Radarr release using the following command. Note that the release the release number and the filename may be different at the time you are following this guide.

sudo wget https://github.com/Radarr/Radarr/releases/download/v0.2.0.299/Radarr.develop.0.2.0.299.linux.tar.gz

After downloading the latest release, we need to extract the tar file using the following command (again change the file name accordingly):

sudo tar -xvzf Radarr.develop.0.2.0.299.linux.tar.gz

3. Configure Radarr to autostart

In order to configure Radarr to autostart, first we need to go to the /etc/systemd/system/ folder:

cd /etc/systemd/system/

Next, we need to create the radarr.service file by running the following command:

sudo nano radarr.service

Paste the following systemd script that enables Radarr to autostart:

[Unit]
Description=Radarr Daemon
After=syslog.target network.target

[Service]
User=root
Group=root
Type=simple
ExecStart=/usr/bin/mono /opt/Radarr/Radarr.exe -nobrowser
TimeoutStopSec=20
KillMode=process
Restart=on-failure

[Install]
WantedBy=multi-user.target

Press Ctrl+x  exit, Y for yes then enter to save.

After saving the startup script, run the following command to enable autostart for Radarr:

sudo systemctl enable radarr

4. Start and Stop the Radarr service

If you used the correct commands, you can go ahead and start the Radarr service you have just created, using the following command.

sudo service radarr start

After starting the Radarr service, you will be able to open the web interface on port 7878. In my case the IP is http://192.168.0.108:7878.
