I tried this earlier today, and the installer is failing at the grub installation when trying to install grub-efi-amd64-signed. I think this is because grub-efi-amd64-signed depends on grub-efi-amd64 2.00-19ubuntu3 and our packages from the ppa are at ubuntu4.
I do, however, see some improvement in behavior in that fioa2 is now seen properly as a gpt partition instead of a loop one. grub-installer: info: Identified partition label for /dev/fioa2: gpt Does an updated version of grub-efi-amd64-signed also need to be in the ppa?
