Package: grub-efi-amd64 Version: 2.04-20 Trying to migrate from MBR to uefi I prepared an ESP (vfat, "esp" tag is set, mounted on /boot/efi) and replaced the grub-pc and grub-pc-bin packages by grub-efi and grub-efi-amd64.
Problem: The postinst script of grub-efi-amd64 seems to update /boot/grub/grub.cfg, but /boot/efi/EFI is not set up. I had to explicitly run grub-install --target=x86_64-efi /dev/sdf That should be the job of the postinst script, as it is for grub-pc. Regards Harri
