Installing KDE on Rocky Linux 9 is easy, as long as you enable the right repositories. One of these have changed since Rocky Linux 8, so if you’ve found a RL8 guide online, you may have been stymied.
Install Rocky Linux and choose either Server with GUI or Workstation under software selection.
Make sure the account you created for yourself is an administrator.
After installation has completed, log in and open up a terminal app.
Add the EPEL Repository
sudo dnf -y install epel-releasePowerTools is now called CRB. This repository has many of the prerequisites that KDE needs.
sudo dnf config-manager --set-enabled crbUpdate packages with the new repositories
sudo dnf -y updateInstall KDE Plasma
sudo dnf group -y install "KDE Plasma Workspaces"Disable the GNOME login screen an enable the KDE login screen
sudo systemctl disable gdmsudo systemctl enable sddmReboot
sudo rebootOnce you reboot, you should be at the KDE login screen.
Make sure to choose Desktop Session: Plasma (X11) or Plasma (Wayland) from the login screen.
Enjoy KDE Plasma on Rocky Linux 9!
Thanks for this! Is there a way to easily remove all the gnome-related packages that are no longer needed?
You’re welcome!
You should be able to run: sudo dnf remove gnome-desktop3
Definitely test first, but I ran on a test VM and all was good afterwards.
