[Bug 1521132] Re: Failed to install Xenial in UEFI mode, failed with "grub-efi-amd64-signed package failed to install into /target/"

[Brett Bogert]

I am also seeing this with the beta2 image.

Non-UEFI installs work fine but any attempt to install with UEFI fails
with the reported error:

The 'grub-efi-amd64-signed' package failed to install into /target/.
Without GRUB boot loader, the installed system will not boot.

I have tried installing to a completely naked SSD (e.g. no partitons created before install)
and was connected to the internet during the install so EFI partition corruption and not 
being connected to the internet don't seem to be the issue.
