was this a black screen with large text advising to login via tt2 (ctrl+alt+F2) as root, then
- Code: Select all
loginctl unlock-session c2
?
if so, it appears that, Plasma DE requires the screensaver to be disabled during the upgrade if un-attended.
this is in the wiki for upgrades.
had there been an issue with the upgrade, you would not know without doing the above.
the upgrade would normally have continued and completed in the background anyway, and would have waited for you to reboot via GUI.
If you had disabled the screensaver, and the prompt appeared, then a bug report should be created.
