[Bug 1899446] [NEW] errors in update to kubuntu 20.04 leads to unusable installation

[random miss]

Public bug reported:

Release: I tried to update from Kubuntu 18.04 (up-to-date, though I
don't know how to tell what version that was) to Kubuntu 20.04.1.

Package version: Unknown.

What I expected to happen: Update.

What happened instead: The update ended due (it said) to having too many
errors. Only firefox and Yakuake (the two programs I had up at the time)
worked at all; I was unable to start anything else. I pressed the power
button to try and reboot; when it turned back on all I got was a black
screen. I was able to type and text appeared on screen but very basic
commands like pwd or ls didn't do anything. My files still exist and can
be accessed though the live usb I'm currently typing from.

I attached the main dist-upgrade log as one of the Ubuntu wiki pages
suggested.

Thank you.
