AFAIK I did NOT have it installed before the upgrade. I was running
Kubuntu with Plasma. Never installed or ran Cinnamon. It just showed up

My question was why did this happen with a *Kubuntu* update?

AFAIK I did NOT have >1 desktop installed before the update. Only used
Plasma since initial install.

Using - systemctl status display-manager.service
gives
sddm.service - Simple Desktop Display Manager
