After upgrading to 16.04 by using the automatic upgrade, the system hangs at startup by prompting " [OK] Started Update UTMP about System Runlevel Changes." and never comes again.

I have no idea what to do ? Any help is welcome.

then enter:

 sudo apt-get install update-manager-core
 sudo do-release-upgrade
