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.
I think nearly all popular ones that come with a graphical interface at all. There is a graphical updater by KDE called Discover that works on a lot of different distros.
