I actually think it must be somehow related to my configuration, because in my previous installation in the same machine (I had to install a fresh new Ubuntu around 2 weeks ago after an HDD major crash), I was able to install nvidia-340 drivers.
The only difference between the old and the new machine configurations are the storage:
>>> PAST: I had a Seagate Barracuda 1TB HDD
>>> NEW: I have a Crucial 500 GB SDD (where OS is installed) and a Toshiba 3 TB HDD
But I don't think this could make any difference on nvidia-340 behaviour
