**Back-Up your existing configuration** before the next step.
**Delete your existing binaries** and replace with the contents of the `.tar.gz` you just downloaded. **DO NOT JUST EXTRACT THE DOWNLOAD OVER THE TOP OF YOUR EXISTING BINARIES, YOU MUST DELETE THE OLD ONES FIRST**. Update your startup script to call `Radarr` instead of `mono --debug Radarr.exe`
**Restore the configuration from the Back-Up** either via the webinterface or by copying the Back-Up files to the install directory.
If Radarr doesn't start make sure you have the dependencies listed [here](https://docs.microsoft.com/en-us/dotnet/core/install/dependencies?tabs=netcore31&pivots=os-linux) installed.
