The grub-efi-amd64-signed package failed to install into/target/. Without the GRUB bootloader the system will not load

Uefi installation always reports an error. Of course, I must have set the efi partition. Still failed. It turns out to be a bug.

It's a bug. /pool/main/g/grub2-signed/grub-efi-amd64-signed 1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd64.debFile rename when you burn it in CD/DVD or usb disk grub-efi-amd64-signed 1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd.deb. As a result installation script can't find the file and failed to install grub. quick workaround is that (if you burn iso in USB flash drive) go to pool/main/g/grub2-signed (in usb flash disk) and rename the deb file manually (add 64). Now boot from usb flash drive and run a disk check to be sure.

If you use a USB flash disk for installation, there is nothing to pay attention to. It's very simple...
