I have experienced the same dreadful situation -- after a routine update the virtual machine was no longer able to reach the login screen. If it helps, I can tell that the system had actually booted all right, since I was able to SSH into the VM and run apt-get -y purge to remove the kernel 4.2.0-30; as far as I can tell it was just the GUI which did not start.

After installation, I am able to log into the system. I then ran the updater application to install the latest updates. After installing the updates and restarting, the system no longer shows any UI after booting. I am now faced with a black screen and a dash that does not blink. The system also does not respond to any inputs. I was able to get back into my system by holding shift to show the GRUB menu and boot using the 4.2.16 kernel.
