Bug Description

Tried to upgrade a 17.04 to 18.04 beta 2, without wiping system. I removed all directories on the SSD except home before the install.

Just error aborted on "grub-efi-amd64-signed failed to install"

SSD is formatted as 3 partitions, bios/swap/root

# fdisk -l /dev/sda
Disk /dev/sda: 477 GiB, 512110190592 bytes, 1000215216 sectors

Your disk is currently partitioned to boot in bios mode, but you booted the installer in EFI mode. A warning message prompted you that this could be a problem and recommended performing a bios mode install instead, but you chose not to. You either need to perform the bios mode install, or partition the disk using GPT and set up an EFI system partition to install in EFI mode. This will be done for you if you choose the "use entire disk" guided install option.

Changed in grub-installer (Ubuntu):
