[Bug 1814134] Re: package grub-efi-amd64-signed 1.93.11+2.02-2ubuntu8.10 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

[huserman]

Fixed.
I am using HP Probook 640 G4. Steps I've done was same which I did during Ubuntu 18.04 installation. 
BIOS-> Security-> Bios Sure Start: 
Uncheck: Boot Keys Protection, Enhance HP Firmware Runtime Intrusion Prevention.., Dynamic Runtime Scanning...

BIOS-> Security-> TPM Embedded Security:
Uncheck: TMP State

BIOS-> Advanced-> Secure Boot Configuration
Uncheck: Enable MS UEFI CA key

I don't know which one of these parameters is causing the problem, but
one of these (most likely the latter) is blocking efi partition.

After performing those steps I was able to perform upgrade without
errors. After the upgrade I've turned back to previous state all the
BIOS changes.
