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”.
You should ideally be updating manually so you can handle any issues as they arise and you don’t wake up to a silently broken system. Manual intervention is occasionally required. Usually it’s associated with a breaking change that’s announced on the mailing list, but sometimes it’ll just happen.
