This shows that your system is running EFI, but that grub has been
blocked from updating the firmware variables to register itself as a
boot option.
Please check if there is a security setting in your firmware that blocks
changing the boot order and disable it.
Without being able to update the boot order, Ubuntu is likely not going
to be able to be booted on your dual-boot system. So it's not a bug
that grub flags this problem before finishing the install, but a bug
with your system that it doesn't support updating the boot order.
** Package changed: grub (Ubuntu) => grub2 (Ubuntu)
** Changed in: grub2 (Ubuntu)
Status: New => Incomplete
