Well hopefully Radarr takes note and improves their users' experience when running on Linux. But in the end it's up to Radarr. Not all software is easily-installable on Windows. Not all software is easily-installable on Macos. Not all software is easy installable on various Linux distributions. I guess until Radarr decides to provide a better user experience for users of Linux, those users will either have to switch operating systems or deal with the difficulties themselves.
