A cup of coffee reset the brain.

A new package needs to be installed.

"linux-image-4.4.0-96-generic"

IOW it is not an upgrade of the package

"linux-image-x.y.p-q-generic"

since it's a new package, with a different name.

Either removing a package or installing a new package requires to run
dist-upgrade/full-upgrade :).
