Xenial: server install from ubuntu-16.04.7-server-amd64.iso. Security updates applied by d-i, including grub-efi-amd64 2.04-1ubuntu44. /etc/kernel/post{inst,rm}.d/zz-update-grub are not present, as with bionic.

grub-pc is not installed.

Enabled -proposed in sources.list.

sudo apt install grub-efi-amd64 grub-efi-amd64-bin grub-efi-amd64-signed

/etc/kernel/post{inst,rm}.d/zz-update-grub now exist as expected

sudo apt dist-upgrade to install 4.4.0-210-generic kernel from xenial-proposed (along with other random bits)

Inspecting /boot/grub/grub.cfg shows references to -210-.

Rebooting, and uname shows -210- is booted.
