Public bug reported: I tried to install trusty on a MacBook Air 5-2 (mid 2012) using EFI. I've tried using both pure EFI boot (holding Alt while turning on the device) as well as rEFIt. No matter which device/partition I select for the bootloader to be installed to, I'm always getting the message "'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB bootloader the system will not load." at the end of the installation and the installer crashes. I also tried mounting /dev/sda1 to /boot/efi beforehand and pointing GRUB installation to /dev/sda1 but no luck. Thus I'm unable to install trusty on this device.
