I recently installed a fresh system with 18.04 as well and have experienced this exact issue when attempting to "apt dist-upgrade" from ssh. In the two instances where systemd was being updated (a few weeks ago and today), my ssh connection was dropped and I'm unable to re- connect to the server. I started the upgrade from a screen session this time and will investigate further when I can get to the console this evening.
