Title:
  GUI X session crash during update from 19.04 to 19.10

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  I was prompted that an update to 19.10 is available so I clicked continue.
  Halfway through the update the whole GUI session crashed and I was left with a white blinking cursor and nothing more.
  Forcibly restarting in this state was a bad idea because this broke the install completely. A kernel panic very early in the boot process appeared. Recovery mode did not work, too.

  Luckily the installation is a VM, so I could easily revert to a working state.
  (VirtualBox 6.0.14 on Windows 10 Home 18.09)

  I decided to try again after uninstalling the VirtualBox Guest
  Additions but no luck - same problem.

  This worked to recover / complete the upgrade:
  ctrl+alt+f3 (in a VM [Host-Key] + f3, by default [right ctrl] + f3)
  login into the tty3 console
  sudo killall dpkg
  sudo dpkg --configure --pending
  ctrl+alt+f1
  login to the GUI session
  restart

  If it wasn't a VM it would probably have required a complete reinstall
  which is the worst possible upgrade experience.
