Can confirm this breaks unattended upgrades of 16.04 devices with hwe installed:

# dpkg-reconfigure linux-image-4.15.0-20-generic
/usr/sbin/dpkg-reconfigure: linux-image-4.15.0-20-generic is broken or not fully installed

# dpkg-reconfigure linux-image-4.15.0-20-generic --force
/var/lib/dpkg/info/linux-image-4.15.0-20-generic.postinst: 50: /var/lib/dpkg/info/linux-image-4.15.0-20-generic.postinst: linux-update-symlinks: not found

However I don't know how it can happen but the grub is modified, and it won't ever reboot.

root@player-3fd4:~# cat /boot/grub/grub.cfg | grep 4.15.0-20-generic | wc -l
10

We have lost hundreds of devices today after reboot with no seemingly possible remote intervention. This is going to be a nightmare for a lot of people...
