I am building a new system and would like to run CentOS 9 Stream with KDE Plasma. There are a handful of tutorials on the web detailing how to install the necessary packages and switch from Gnome to KDE; the best representation of these tutorials is probably the one at
LinuxCapable.com.
All of the tutorials boil down to enabling a few repos and then using dnf to install the "KDE Plasma Workspaces" group of packages. I have a fresh install of CentOS 9 and I just cannot get this to work.
All of the necessary packages are supposedly available in EPEL. With just the EPEL repo enabled, I get the following errors when I attempt to install the packages:
Code:
[81bones@localhost ~]$ sudo dnf groupinstall "KDE Plasma Workspaces" -y

No match for group package "k3b-extras-freeworld"
No match for group package "gstreamer1-plugins-ugly"
No match for group package "gstreamer1-plugins-bad-freeworld"

Some tutorials include instructions to enable the EPEL-Next repo. Unfortunately this still doesn't work. With the EPEL-Next repo enabled, I get this error:

I haven't tried to use the --nobest or --skip-broken options yet, and I'd really prefer not to. With a fresh install, it would be nice to have everything working properly with all the necessary packages to start out. None of the tutorials or other posts describing how to install KDE discuss issues like this.
Does anyone have any thoughts on what the problem might be? Perhaps the repo developers are just in between package rollouts and it's just dumb luck that I happen to be trying to install KDE right now (and after a week or two the problem will fix itself)?
