I can not believe that still, after many years Discover still has crash issues. Using non-KDE Manjaro, Mint and other distros their update manager is rock solid.
Plus those other distros have a way to use a GUI to search for the fastest server located in your country of origin.
I don’t understand why?
I’ve written a few blog posts may help to explain things.
First, from a general perspective: “Why don’t you just fix [thing] already?” – Adventures in Linux and KDE.
Next, in slightly more technical detail: Where bugfixes and new features come from – Adventures in Linux and KDE
Hopefully those help to shed light on how development and resource prioritization work in a mostly-volunteer-based open-source community.
