I experienced the same issue on a fresh KDE Neon User Edition install from today too. It prevents me from developing KDE Software due to other frameworks failing to find KCoreAddons 5.90.0
I can confirm this issue too, cannot build any KDE apps now.
Sorry about this, should be fixed now, you may need to upgrade twice once to get the new pin file and once more to get the new kcoreaddons packages
Get this issue again. After trying to start plasmashell: > qt.qpa.xcb: could not connect to display > qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even through it was found After trying to reinstall qt5dxcb-plugin: > Broken qt5dxcb-plugin:amd64 Depends on qt-base-abi-5-12-8:amd64 < none @un H > > Considering libqt5core5a:amd64 as a solution to qt5dxcb-plugin:amd64 99999 > qt5dxcb-plugin: Depends: qt-base-abi-5-12-8
Can't reproduce on a clean install, so I just reinstalled the system.
Figured it out! I have KDE neon Developer Edition installed on VirtualBox, and the issue appears after installing VirtualBox Guest Additions.
