You misunderstand my complaint. I am not blaming anyone. I am explaining why the user experience is bad. This is a common retort in the Linux community: "but they are to blame, not me!" As an end user, I don't care who is to blame. I just care that Linux is harder to use.
Why are directing this complaint against Linux and not Radarr? They could choose to package it for various Linux distributions if they do wish.
