Title:
  package grub-pc 2.02-2ubuntu8.10 failed to install/upgrade: installed
  grub-pc package post-installation script subprocess returned error
  exit status 1

Status in grub2 package in Ubuntu:
  Invalid

Bug description:
  I wasn't watching the screen so didn't see any issues.

  I know a `sudo apt dist-upgrade` was running with liferea window open
  & I was away from screen; the machine hadn't been on for long but am
  happy to provide more information from system if helpful.

  The 'summary' is apport-created, and a very similar one is
  https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1794519 but it
  was marked to a different package so I clicked 'no add new'

  the box is x86_64, but install was x86 (needed it x86 for a kernel bug
  test as this machine which would not boot qa-test daily-ISO's in x86;
  `uname -a` shows 4.18.0-10 where I expected 4.15 so I failed to
  backout later [test] kernel change sorry)
