Bug Description
Attempting to boot under secure boot/uefi on trusty ESM with the following packages installed:
$ dpkg -l 'grub*' | grep ^ii
ii grub-common 2.02~beta2-
ii grub-efi-amd64 2.04-1ubuntu42 amd64 GRand Unified Bootloader, version 2 (EFI-AMD64 version)
ii grub-efi-amd64-bin 2.04-1ubuntu42 amd64 GRand Unified Bootloader, version 2 (EFI-AMD64 modules)
ii grub-efi-
ii grub2-common 2.02~beta2-
ii grub2-themes-
and with all GRUB_HIDDEN options disabled in /etc/default/grub:
$ grep ^GRUB /etc/default/grub
GRUB_DEFAULT=0
GRUB_TIMEOUT=10
GRUB_DISTRIBUTO
GRUB_CMDLINE_
GRUB_CMDLINE_
results in grub being unable to display the grub menu when booting. Pressing Esc also does not cause the menu to display; however, it is being recognized as it cause grub to stop its countdown (and thus never boot).
This is a regression in that the same set of options with the prior round of updates published in the trusty ESM archive will successfully bring up the grub menu on boot, with the following packages installed:
$ dpkg -l 'grub*' | grep ^ii
ii grub-common 2.02~beta2-
ii grub-efi-amd64 2.02~beta2-
ii grub-efi-amd64-bin 2.02~beta2-
ii grub-efi-
ii grub2-common 2.02~beta2-
ii grub2-themes-
