RHEL 8.2 and CentOS 8.2 have an updated qt5. This updated qt5 allowed us to update the KDE Plasma Desktop in EPEL8. We are not at the following versions.
qt5 - 5.12 plasma - 5.18 [1] kf5 - 5.68 / 19.12 apps - 5.18 / 19.12
Installation Instructions: ### First: install epel-release rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
### Second: Enable codeready-builder or PowerTools subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms #### If CentOS 8 do dnf config-manager --enable PowerTools #### If CentOS Stream do dnf config-manager --enable Stream-PowerTools
### Third: install KDE dnf group install "KDE Plasma Workspaces" or dnf group install kde-desktop (Optional) dnf group install kde-media (Optional) dnf group install kde-apps (Optional) dnf install okular
### (Optional) Fourth: Set sddm as desktop manager ### Required if you started from a minimal install systemctl set-default graphical.target [if in multi-user.target] dnf install sddm* systemctl enable sddm -f reboot
### (Optional) If you installed in GNOME systemctl reload gdm
Known Issues: Several (about 50%) settings do not work in System Settings. https://bugzilla.redhat.com/show_bug.cgi?id=1838801 Help resolving this bug would be appreciated. It is irritating, but not critical.
Many thanks to all who helped with this. Troy Dawson
[1] plasma-nm is currently at 5.15. This has been verified to work. We will hopefully be able to update it to 5.18 within a month.

Hi, I'm testing Centos 8.2 in a VM with VirtualBox-guest-additions-6.1.10-3.el8.x86_64, seems to me that undefined symbol: _ZN15KStandardAction25switchApplicationLanguageEPK7QObjectPKcPS0_ don't let me start KDE [1] .
Any guess ?
Thank you

Is this a fresh install of CentOS 8.2 or an update of something older? How did you install kde? If it's a fresh install, did you do an update after the install?
Although the only virtual machines I've tried it on is KVM based ones, I don't *think* this is a VirtualBox vs KVM issue. It seems to be a too-old or too-new library issue.
My guess: You updated from CentOS 8.1 to 8.2. You have rpm-fusion installed, and there is some package in rpm-fusion that hasn't been rebuilt yet. Whatever those packages are, are preventing a complete update to CentOS 8.2, and whatever isn't updated is affecting kf5-plasma from starting. It's a total guess, and I'm not meaning to pick on the rpm-fusion people, but since CentOS 8.2 just came out, it's possible they don't have everything finished yet.
Hope this helps. Troy

I installed Centos 8 with CentOS-8.1.1911-x86_64-boot.iso. Today after doing dnf distro-sync which installed 18 Packages and upgraded 683 Packages, it starts to work correctly .
Thank you
