Last time I tried updating Ubuntu on my parents' PC, it completely fell over because it tried to throw up a dialog on a console in the middle of the update, even though I was doing a GUI update. When I killed that (uninteractible, permanently froze the update) process, the system autorebooted in a desktopless state. Now, I knew to use `dpkg --reconfigure` from a root shell to fix this, but a layman would have been stumped and had to reinstall. 2021 at least was not the year of the Linux desktop in our household.

(Let alone the dozen of small KDE issues we've had over the years. It's really easy to get that desktop in an uninteractible state if you click the wrong things.)
