after updating my Leap 42.1/KDE system to the latest Framework and Plasma last weekend (yes, I know, that’s long ago, but I was busy.) plasmashell or Plasma desktop doesn’t load any more. Instead I get I rather cryptic bug-message (or better: two of them) for the two plasma containers on the desktop. The message for the desktop runs like this (sorry, it’s partly in german):
Fehler beim Laden der QML-Datei file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:29:1: plugin cannot be loaded for module “org.kde.kquickcontrolsaddons”: Cannot load library /usr/lib64/qt5/qml/org/kde/kquickcontrolsaddonsplugin.so:(/usr/lib64/qt5/qml/org/kde/kquickcontrolsaddons/libkquickcontrolsaddonsplugin.so: symbol _ZN17QQuickPaintedItem10itemChangeEN10QQuickItemChangeERKNS0_14ItemChangeDataE, version Qt_5 not defined in file libQT5Quick.so.5with link time reference)
These messages appear whether I am in my user account or in root. KDE is unusable.
Since I can still access the command line, my question is: Is there hope that I can correct this by just updating FW and Plasma with newer versions? And if, which commands should I use?
I know it’s something with zypper, but which one?
Thanks for your help!
