I heard that Manjaro has greatly diverged from Arch over the last couple of years. Someone said EOS, which I think stands for Evolution Operating System is closer to Arch now, but I haven’t actually looked into it so idk how accurate that is. Arch takes more work to get set up than Pop does though, just FYI if you’re considering it. It doesn’t come with anything by default, unless you use a script to install.

You're talking to someone who used to be an Arch user. It's nothing actually specific to arch, it's an initiative by KDE. People link to arch wiki because the wiki is a good source, and also because arch has more up to date packages than pretty much everything else.

Sorry, I don’t actually know how to do it. I was wondering if you can use the instructions on that page but change the package name to the latest package name. That would definitely install it, but I don’t think it will work. Based on what I read after commenting, Ubuntu LTS doesn’t have the required dependencies, and Pop is based on Ubuntu LTS. It should be available in the next version though.

Is it actually a different package name? That's not how these types of things normally work. Either the new version is in the repos or it isn't. The package name doesn't container the version number either, it's just kde-standard. I believe KDE 6 isn't in the standard Ubuntu repos at all, even for 24.04, which is newer than the one Pop OS is based on. It seems you have to use KDE Neon to get 6 on an Ubuntu based system.
