I haven’t distro hopped much in the past few years, so I am near clueless. I know that Linux Mint has a graphical updater and I vaguely remember openSUSE having it, though I’m not so sure on that one, because as I mentioned, it’s been a while. Especially curious if any Arch-based distros have it.
not so much a specific distro. I know KDE has its own graphical updater in the “discover” app store, COSMIC DE also has its own app store. personally I always update my apps through the terminal as its just faster and easier.
