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... 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:
