[ubuntu] do-release-upgrade -d and now my server won't boot

I have an Ubuntu server and last week I ranand it did the upgrade perfectly. It also did every other upgrade for the last 2 years no problem. When the upgrade finished and it rebooted, I SSH into it and it told me again there is an update. But when I run the command again it tells me there's no upgrade available. I searched around on Google for a reason and found you can runas another way to upgrade. So I ran it. Afterwards I rebooted and now I can't SSH into it anymore. Any idea why? The server is on site about 30 minutes away so I won't be able to look at it until tomorrow, is there any way to fix this remotely? Thanks.
