For full disclosure, this is in a "cross" build environment (qemu-static). this works for other versions of ubuntu and has worked for xenial in the past.
the error messages seem to indicate 'update-initramfs' was deferred, but the the postinst tried to copy it into place even though it wasnt there. I am able to hack around this error by just touching the file /boot/initrd.img-4.3.0-7-generic before runnign the apt-get install. Setting up linux-image-4.3.0-7-generic (4.3.0-7.18) ...
