During this upgrade, several other packages may be of interest, because some are related to EFI handling:
efibootmgr:amd64 (0.9.0-2, 0.11.0-3) << especially this one grub2-common:amd64 (2.02~beta2-18, 2.02~beta2-19) grub-common:amd64 (2.02~beta2-18, 2.02~beta2-19) grub-efi:amd64 (2.02~beta2-18, 2.02~beta2-19) grub-efi-amd64:amd64 (2.02~beta2-18, 2.02~beta2-19) grub-efi-amd64-bin:amd64 (2.02~beta2-18, 2.02~beta2-19) libefivar0:amd64 (0.15-2, 0.15-3) << and this one The bug may be related to the use of new features in these new versions, probably in libefivar0, but this is only my guess.
