[Bug 2015401] Re: package grub-efi-amd64-signed 1.187.3~22.04.1+2.06-2ubuntu14.1 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 32

[Steve Langasek]

The target for installing EFI GRUB must be an EFI System Partition, not
a disk.  GRUB does not a priori know whether the device you've specified
is correct.

The value of this field is supposed to have been populated for you by
the installer at install time.  So I don't think there's much here we
can do to improve this, aside from the error message presented by the
postinst ("/" is not the name of an ssd).

Bug description:
  During the software update debconf-communicate window (configuring
  grub-efi-amd64-signed) showed up asking me to select the grub
  location. I researched but didn't find a solution online for what I
  should choose. I ended up choosing the SSD with the boot/efi but the
  next window it wouldn't continue (there was a check box saying
  continue without installing grub). So I went back and marked both SSDs
  and pressed next. Now it shows me window saying the installation of
  the software failed. I hope it didn't mess up my Grub loader; I have a
  dual boot system for Windows and ubuntu Linux.
