When prompted to choose a target for grub, what did you answer?

> mount: /var/lib/grub/esp: special device /, does not exist.

This output effectively indicates you have somehow configured grub to not know what EFI System Partition to install to.

Please attach the output of 'debconf-show grub-pc'.
