XServer doesn't start after upgrade to 17.10

After upgrading from 17.04 to 17.10 (using the UI "Software Updater"), the computer booted normally but the XServer could not start. During boot, the screen would go black for a few seconds, return back to the systemd output (tty1) for a few seconds and then go black again. This continued indefinitely.

FIX: I rebooted the system into runlevel 3 and went to log in via tty1. I tried to manually running "startx", which had the same result as described above. In the "/var/log/Xserver.0.log" I found an error reading "Could not load nvidia module" (paraphrasing).

I checked the ubuntuusers wiki (https://wiki.ubuntuusers.de/Grafikkarten/Nvidia/nvidia/) and saw that the current driver-version for my card (Nvidia GTX 1070) is "nvidia-384". My installed version was "nvidia-376". I uninstalled the old version and installed the newest version, rebooted the system and all was well.

After the reboot and successful login in in Gnome Shell, I got the standard Ubuntu error-report dialog, saying "nvidia-376 could not be compiled" (paraphrasing).

PROPOSAL: The upgrade-agent should have checked for a newer version of the package and informed me, that the old package-version might not compile against the new kernel/headers.

I understand that the nvidia driver is proprietary software and all, but this has happened in every upgrade I have made so far.
