Just upgraded an instance of Ubuntu Server 16.04 to 18.04 and the install hangs at boot, last line emitted to the terminal is Welcome to Ubuntu 18.04!
Instance is a VM on an R2008 HyperV.
I suspect this hang is a result of the original appliance configured as a 32bit system and 18.04 only supporting 64bit, just a hunch.
Most recent snapshot is from 10/2017 (so much for backup policies).
I wouldn't be shocked if recovering this instance isn't possible, Has anyone gone through this? Is it possible to extract the install and run it from another appliance or at the very least recover some of the application data into another proper 18.04 instance?
