package grub-efi-amd64-signed 1.139+2.04-1ubuntu24 failed to install/upgrade: Hyper-V VM Type 2 with Secure Boot with EFI password

[Donovan Finch]

Hyper-V VM type 2 with the Secure Boot with EFI signing password.
Installed using the GUI installer, setting the EFI password when prompted.

System boots fine.

On 'apt upgrade', new grub2-signed post-install script didn't prompt for the password, that may be what went wrong.
