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.
What distro doesn’t? Beside a couple probably.
From my experience, most of Arch derivatives.
CachyOS comes with two. Manjaro comes with one. Not sure if Endeavour has one or not now.
NixOS
