[Scorpion]

Some errors while i' m updating to Ubuntu 18.04 from 16.04 (now is updating to the 17.10 version) using

sudo apt update && sudo apt dist-upgrade
sudo apt install update-manager-core
sudo do-release-upgrade

I' m updating because i can' t use cuda 9.2 if i use the nvidia-396 drivers which have cuda 9.2 i can' t login (i' m bounced back).
