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.
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-$(arch)-rpms
# CentOS Stream 9
dnf config-manager --set-enabled crb
dnf install epel-release epel-next-release
subscription-manager repos --enable codeready-builder-beta-for-rhel-9-$(arch)-rpms
# 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
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
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
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.
