[Bug 1767259] Re: ubuntu 18.04 The 'grub-efi-amd64-signed' package failed to install into / targer.

I also experienced this (Ubuntu 18.04, x64, with EFI enabled on an HP
Laptop).

During install, I do not have an internet connection enabled.
Both checkboxes were disabled:
  - "Download updates..."
  - "Install third-party software..."

Questions:
a) Is the package "grub-efi-amd64-signed" simply not included in the Live CD?
   [WOULD SOMEONE PLEASE CHECK AND POST THE ANSWER IN THIS BUG REPORT?]

   If this is the case:

   Would executing the following in a live session before launching Ubiquity solve the problem?...
     $ apt install grub-efi-amd64-signed" before launching Ubiquity solve the problem?

   Should the Live CD come shipped with this package?
   Should the ubiquity package be updated to include
     grub-efi-amd64-signed as a "depends" or "recommends"?

...or...

b) Does the Ubiquity installer need a newer updated version of this package?
   [WOULD SOMEONE PLEASE CHECK WHICH VERSION IS INSTALLED AND POST IN THIS BUG REPORT?]

   If this is the case:

   Would executing the following in a live session before launching Ubiquity solve the problem?...
     $ apt update
     $ apt install grub-efi-amd64-signed" before launching Ubiquity solve the problem?

   Perhaps Canonical needs to issue a point release Live CD (version 18.04.1?)
     with an updated version of this package?
