I am currently using EndeavourOS, but am annoyed by the constant daily updates of 1GB and pacman not installing important dependencies automatically (ex: spell checker for document editor). I like the way Fedora works: you update whenever, important dependencies are downloaded automatically, and packages are recent-ish, but I don’t like that it takes forever to run dnf. I don’t want to use Manjaro (apparently it breaks quickly?), and the distro needs to support KDE. I know about Flatpak, but I don’t want to download 1GB of data for each app. Are there any good options?
(Yes, I can probably deal with Fedora, but dnf is slower than apt, and I don’t want to deal with external repositories for non-free software.)
EDIT: I do not want to tweak or edit configuration files, I just need something that has up to date packages and “just works”.
There’s openSUSE tumbleweed. It’s rpm based like fedora and it’s rolling-release like arch. I don’t know what the 3rd party/nonfree software situation is like. Maybe someone else can chime in on that front.
I will add, as an arch user, I think you could easily tweak your current system to be less annoying with the updates, but I realize that’s not the question you’re asking so feel free to disregard that.
OP is complaining about dnf being too slow. I’ve heard zypper is even worse.
