Hello Emma, this sounds a lot like a bug I experienced when upgrading from 16.04 LTS to 18.04 LTS: https://bugs.launchpad.net/ubuntu/+source /ubuntu-release-upgrader/+bug/1768379
This bug should have been fixed yesterday, though. Can you explain how your upgrade happened? Did you notice any error messages along the way? Can you please run apport-collect 1781663 once you've gotten a working command prompt?
