Tks Kai, you where right.
The image-extra package was missing
I installed it and now everything is ok
gmellini@goblinshark:~$ sudo apt-get install linux-image-extra-4.4.0-67-generic
Really don't know why was not installed during the upgrade.
I tried to check and install linux-generic metapackage but I didn't found
gmellini@goblinshark:~$ dpkg-query -l linux-generic
dpkg-query: nessun pacchetto corrispondente a linux-generic
I can confirm that now the problem is solved, tks for your support
