Title:
  package grub-pc 2.02-2ubuntu8.21 failed to install/upgrade: installed
  grub-pc package post-installation script subprocess returned error
  exit status 10

Status in grub2 package in Ubuntu:

Bug description:
  Hello,

  I started having many kinds of updating and upgrading problems after I
  tried to install Jitsi Meet to my Ubuntu.

  Here are some of them (Sorry, they are in Finnish):

  Tehdään asetuksia: libldap-common (2.4.45+dfsg-1ubuntu1.9) ...
  Tehdään asetuksia: grub-pc (2.02-2ubuntu8.21) ...
  dpkg: error processing package grub-pc (--configure):
   installed grub-pc package post-installation script subprocess returned error exit status 10
  Tehdään asetuksia: libldap-2.4-2:amd64 (2.4.45+dfsg-1ubuntu1.9) ...
  Tehdään asetuksia: libldap-2.4-2:i386 (2.4.45+dfsg-1ubuntu1.9) ...
  Käsitellään paketin libc-bin (2.27-3ubuntu1.4) liipaisimia...
  Käsitellään paketin man-db (2.8.3-2ubuntu0.1) liipaisimia...
  Käsittelyssä tapahtui liian monta virhettä:
   grub-pc
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  This what happened now, gave me this kind of announcement:

  Error while installing package: installed grub-pc package post-
  installation script subprocess returned error exit status 10

  I have Ubuntu 18.04 LTS
