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.
