[Bug 1971059] Re: package grub-efi-amd64-signed 1.180+2.06-2ubuntu7 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 32

[Steve Langasek]

This partition was created at install time because it is impossible to
determine from a CD image booted at install time in BIOS mode whether
the system will boot in BIOS mode from an internal disk.  We therefore
always install BIOS and EFI bootloaders both, when installing on x86.

You have forcibly removed the partition that was created at install time
(the partition that grub2-efi-amd64-signed knew it had installed to
previously and should update on upgrades).  The package then quite
reasonably refuses to upgrade since it can't find the target disk to
actually install to.  That is not a bug in the package.

** Changed in: grub2-signed (Ubuntu)
       Status: Confirmed => Invalid
