TrueNAS: Radarr Manual Install
Radarr is an absolute essential tool to include in your FreeNAS setup and to have installed in a jail. Radarr is an independent fork of Sonarr, reworked for automatically downloading movies via Usenet and BitTorrent. Radarr can integrate directly into your media server setup and integrates directly with most modern download clients: uTorrent, Deluge, rTorrent, NZBGet, SABnzbd, qBittorrent, Transmission and many more. It will determine when the file has been downloaded an move it to the correct media folder to be picked up by media servers such as Plex and Emby. The project was inspired by other Usenet/BitTorrent movie downloaders such as CouchPotato. When first setting up FreeNAS it was Radarr that was causing me the most problems, largely because I had Radarr in its own jail and had problems with ensuring consistent path names in configs (qBittorent and Radarr) and ensuring that file permissions were correctly setup. This article will show you how to install Radarr within an existing jail (e.g. with your OpenVPN connection and a torrent client) in the most simple way to avoid path and file permission problems that I have previously experienced. With that, lets get on with a Radarr manual install by following the directions in the article.
This is part of my ongoing series of TrueNAS and FreeNAS setup, configuration and install articles.
Radarr Manual Install
First we need to make sure that everything is up to date using the following commands from the shell within the jail in which you are installing Radarr:
Next we can get the package manager to install radarr with the following command:
pkg install radarr
Wait a couple of mintues for it to install Radarr and all its dependencies.
First we will need to enable the Radarr service and allow it to run at startup with the following command (again from within the jail’s shell):
I was having security problems, so I want Radarr to run as root, not as the user ‘radarr’ which it is set to as default. To do this I edited the
/usr/local/etc/rc.d/radarr file and changed:
Of course you can keep the users as ‘radarr’ or change it to whatever user you like, just will just need to pay close attention to the securities and how they relate to the securities in the larger FreeNAS system (e.g. match UIDs and GIDs).
We can now start radarr:
service radarr start
Once it has started, you can open the WebUI at
Ensuring Future Updates
We need to make sure Radarr knows where to run mono from for future updates. If you don’t do this step you will get an error like:
System.ComponentModel.Win32Exception: ApplicationName=â€˜monoâ€™, CommandLine=â€™â€“debug /tmp/nzbdrone_update/NzbDrone.Update.exe 7274 /tmp/nzbdrone_update /usr/pbi/radarr-amd64/share/radarr/NzbDrone.exe /data=/var/db/radarr/nobrowserâ€™, CurrentDirectory=â€™â€™, Native error= Cannot find the specified file
The issues is a path problem and thankfully the fix is quite simple. Simply enter the shell of the jail running Radarr and enter the following command:
ln -s /usr/local/bin/mono /usr/bin/mono
I won’t provide all the information on how to configure Radarr as there are a number of guides out there and they don’t need to be OS specific. I will however provide a couple tips which can help.
First, I had trouble for a while with qBittorrent removing the torrent when done. Radarr does not like it when you tell it to remove automatically (presumably as it needs time to note the download is complete and copy it). Instead, you need to tell qBittorrent to ‘pause’ when the download is complete.
From the qBittorrent web interface, go to
Tools -> Options -> Bittorrent Tab. Under the ‘Share Ratio Limiting’ heading the drop box beside where it says ‘then’ select ‘pause them’. Now put a tick beside ‘Seed torrents until their ratio reaches’ and set the value to whatever you want. ‘0’ would mean it would pause as soon as the download is complete and ‘1’ would mean as soon as it has shared an amount equal to the size of the file. Using ‘0’ is frowned upon in the torrenting community. **Scroll to the bottom and click ‘Save’**
Second, when setting up Radarr with Jackett, you do not need to individually add each URL for each search provider. Instead copy one (by clicking the ‘Copy Torznab Feed’ button) and pasting it into URL location in the Radarr config as shown in the image below.
You will need to edit the URL put in by removing the name of the search provider embedded with the URL and replacing it with ‘all’ as shown below:
You will of course need to insert your API key and any other configuration necessary.
So with this short, simple and straight forwards article on the easiest way to manually install Radarr within an exising jail, you should now be off to the races in terms of automatically getting movies onto your Plex or Emby media server.

Appreciate the right up. Any chance this could be updated to include updating Mono or perhaps a separate right up on how to update Mono on Truenas. Iâ€™d guess it to be pretty universal for Radarr, Sonarr, etc.
I’m getting this notice n the Radarr app:
Please upgrade to the .NET Core version of Radarr, Mono versions will not be supported in the next release.
Is this something you’ve figured out yet?
I can look into it. Sadly my test box has died and I’ll need to find something else to test on!
Hello, I would be very greatfull if you can update or make new guide with .net.
Hey there! I’m also looking for some sort of guidance for upgrading from mono to .NET. There’s now official documentation to install Radarr, but that’s for a fresh install.https://wiki.servarr.com/radarr/installation#freebsd
