[Bug 1775743] Re: [regression] Cosmic daily images 20180606-11 install but boots only to grub prompt on EFI systems

[Łukasz Zemczak]

It looks like the grub2-signed upload is the culprit, looks like the
dependency switch we made caused in the d-i cases for grub2-efi-amd64
not to be installed, even though it's required. Will be consulting a
fix.
