For those of you who want to use KDE on RHEL9 Beta, or CentOS Stream 9, it is available via EPEL. It is currently plasma 5.23.5, kf5 5.90.0, qt5 5.15.2. There might be an update before RHEL 9.0 is released.
There is currently a critical selinux bug[1] that prevents KDE from starting. That is the reason I have not sent this out earlier. When that get's fixed, I'll update these instructions.
Note: All these steps should be done as sudo or root.
Step 0 - Manually fix selinux bug setsebool -P selinuxuser_execmod 1
Step 1 - Enable CRB and Install epel-release [2] # RHEL 9 Beta subscription-manager repos --enable codeready-builder-beta-for-rhel-9-$(arch)-rpms dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
# CentOS Stream 9 dnf config-manager --set-enabled crb dnf install epel-release epel-next-release
Step 2 - Install KDE dnf group install "KDE Plasma Workspaces" or dnf group install kde-desktop
There is a bug in the epel9 comps file (my fault, fixing now), so "KDE Plasma Workspaces" will not work without an exclusion. So, for the next week or so, use the following to install the KDE Plasma Desktop from epel9 dnf --exclude=rhc group install "KDE Plasma Workspaces" or dnf group install kde-desktop
Step 2.a - (Optional) Install other kde groups dnf group install kde-media dnf group install kde-apps dnf install okular
Step 2.b - (Optional) Set sddm as desktop manager dnf install sddm* -y systemctl enable sddm -f
Step 3 - Ensure you boot into graphical mode systemctl set-default graphical.target
Step 4 - Reboot and enjoy
It is recommended that you log into the Plasma (X11) vs Plasma (Wayland). There are several non-critical wayland bugs. These bugs are being addressed but aren't expected to be fixed until the RHEL 9.1 timeframe.
