Over the weekend I decided (perhaps stupidly) to update my Ubuntu 18.04 VM to Ubuntu 20.04, and now I can't connect to it.
The machine starts up ok in Hyper-V, but the connection just hangs on the Hyper-V loading screen.
A little investigation in PowerShell showed me that the machine doesn't appear to have an IP address assigned to it, and trying to use the "Shut down" option through Hyper-V errors with the message
'VM' failed to stop. The device is not ready for use.
I'm kind of stuck as to what to try next, is there any hope for my VM, or have I managed to create a (virtual) paperweight (to keep all my emails from flying away).
Network adapter is set to "Default switch", as networking really isn't my forte, and until now, it seemed to work fine.
