Title:
  distupgrade kubuntu 25.10 to 26.04 fails; many broken kde package
  dependencies including plasma-desktop

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  When performing a dist-upgrade from 25.10 to 26.04, the upgrader detects 39 broken kde packages.
  Since I created a snapshot (it is a vm on proxmox) beforehand, I can easily rollback.
  I could possibly start a new VM with clean install, but I would prefer to distupgrade.
