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.
