  grub boot error : "symbol 'grub_calloc' not found

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_callow' not found.
  Entering rescue mode...

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