A couple thoughts, as it's getting late... I've pasted the latest versions available to a KDEneon distro below, ready to run. Maybe try these (might require a --reinstall switch passed), see if there are fewer broken packages afterwards?: apt install grub-efi-amd64-bin=2.06-2ubuntu14.1 apt install grub-efi-amd64-signed=1.187.3~22.04.1+2.06-2ubuntu14.1 apt install gwenview=4:22.12.3-0xneon+22.04+jammy+release+build15 apt install kdeconnect=22.12.3-0xneon+22.04+jammy+release+build22 apt install kwin-x11=4:5.27.3-0xneon+22.04+jammy+release+build33 apt install kwin-common=4:5.27.3-0xneon+22.04+jammy+release+build33 apt install kwin-data=4:5.27.3-0xneon+22.04+jammy+release+build33 apt install libkf5filemetadata-bin=5.104.0-0xneon+22.04+jammy+release+build15 apt install libkf5sysguard-data=4:5.27.3-0xneon+22.04+jammy+release+build19 apt install plasma-nm=4:5.27.3-0xneon+22.04+jammy+release+build20 apt install shim-signed=1.51.3+15.7-0ubuntu1 BONUS: apt install neon-desktop=4+p22.04+trelease+git20230227.1438 ## kwin-wayland ## kwin-wayland-backend-drm
