Title:
  grub boot error : "symbol 'grub_calloc' not found

Status in grub2 package in Ubuntu:
  Confirmed
Status in grub2 package in Debian:
  New

Bug description:
  After updating grub2 (to 2.02~beta2-36ubuntu3.26) and rebooting, my
  server does not boot:

  Booting from Hard Disk 0...
  error: symbol `grub_calloc' not found.
  Entering rescue mode...
  grub rescue> _

  I rebooted 3 servers in this way (all running Ubuntu 16.04.6 LTS) and
  all hung.

  A lot of other people are reporting the same problem at:

  https://askubuntu.com/questions/1263125/how-to-fix-a-grub-boot-error-
  symbol-grub-calloc-not-found.

  Above most likely means that dpkg debconf no longer knows about the
  correct drives to install grub onto.

  Please boot & mount all the target disks and execute

  $ sudo dpkg-reconfigure grub-pc

  You will be asked which drives to install grub onto, and then grub
  will be installed onto them, and more importantly, it will remember
  where to install grub to, on all future upgrades.
