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.
openSUSE Tumbleweed has a graphical installer you can use to install, remove, update applications, browse, search, etc. But you still need to run a command line ‘zypper dup’ to fully update the system.
Tumbleweed has Myrlyn or Discover.
I’d forgotten about Myrlyn. I guess I never switched over to it from the older YaST software updater, which does not have the equivalent of ‘zypper dup’. But from what I read now, Myrlyn does, so that is good.
Discover does not, however. Not only does it not do the equivalent of ‘zypper dup’ it does not resolve package conflicts that can arise with external repos.
For anyone reading whose not familiar, on Tumbleweed, ‘zypper dup’ (or the Myrlyn equivalent) is what you need to run periodically to update to the latest snapshot (and being a rolling distro, new snapshots come out anywhere from every day to every few days, depending how the automated testing goes).
