Title:
  Upgrade from 18 to 20 hanging at "pregenerating context..."

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

Bug description:
  Hi.

  I've just done the upgrade from bionic to focal using the GUI upgrade tool.
  Upgrade hung after the terminal printed the line "Pregenerating Context MarkIV format. This may take some time...".

  I found an answer on the web that I need to press Enter few times,
  which worked, but otherwise I would break the upgrade in an unstable
  state.

  I expect the script to be fully automatic, without waiting for my
  blind confirmations.

  Thank you.
