Public bug reported: I have just upgraded from Ubuntu 18.04.4 LTS (Bionic Beaver) to Ubuntu 20.04 LTS Focal Fossa.
There is the official graphical way to upgrade. I have used that. https://ubuntu.com/tutorials/tutorial-upgrading-ubuntu-desktop#1-before-you-start At the end I had two packages that didn't install - the shim-signed was one of them. The package number is 1.40.3+15+1533136590.3beb971-0ubuntu1. I have an AMD64 processor - namely AMD Quad-Core A4-6210. Error message: Setting up grub-efi-amd64-signed (1.142+2.04-1ubuntu26) ... dpkg: error processing package grub-efi-amd64-signed (--configure): installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 10 dpkg: dependency problems prevent configuration of shim-signed: shim-signed depends on grub-efi-amd64-signed | grub-efi-arm64-signed; however: Package grub-efi-amd64-signed is not configured yet.
