[Bug 1822395] [NEW] do-release-upgrade dies cosmic to disco (x crash to empty pty)

[Robert C Jennings]

Public bug reported:

I performed a 'sudo do-release-upgrade --devel' from cosmic to disco
tonight under X from gnome-terminal.  In the middle of the upgrade the
screen changed from X to a black screen with a unblinking text cursor in
the upper left corner.  CTRL-ALT-F[1-9] did nothing and I heard the CPU
fan spin down (it had been on during the entire upgrade).  After 10m I
held down the power button and forcibly powered the machine down.
Powering on the machine it booted to a getty on a pty where I logged in
and sudo'd to root.  I ran 'apt-get install -f', 'apt full-upgrade', and
lastly 'apt autoremove --purge', then I rebooted and things came back to
life.   The system seems happy now.
