[Bug 1645149] Re: When trying to install Lubuntu 16.10 from USB Key using UEFI, getting error on grub2 install

[Vlad]

@psusi thanks for responding. Unfortunately, negative on that. It's true that I had a network drop then, but I kept trying (with or without updates checked) dozens of times. Grub2 fails to install no matter what.
I bypassed the bootloader requirement by installing rEFInd and loading vmLinuz image at boot, but didn't manage to get past this grub package bug.

basically, it refuses to install the efi-signed package to /target/ no
matter what.
