Bug description:
  This is most likely from the failed upgrade attempt from Ubuntu Studio to Bionic Beaver.
  I was simply following the prompts to report bug.

  Was thinking of doing the following: sudo apt-get auto-remove to
  remove unsigned kernels then try the upgrade again, could you please
  confirm if this is a valid course of action.
