Unfortunately `Esc` is not working to show me what's going on. It literally hangs there with no other ability to get output (and ssh is dead at that point).
I've used `halt` because poweroff/shutdown hasn't been working reliably. Reset seems to work more reliably, but will not even work once I've issued a "Shutdown".
In the past `halt` has effectively shut down the Proxmox VM entirely such that I can restart it again.
`Poweroff` is hanging the system. It appears as though it's not initiating the actual shutdown or not completing it entirely. Yes, there is something wrong here and this is the 3rd instance of Ubuntu 18.04 that I've installed and that is experiencing this. There has to be some better way of tracking this down. I suppose I need to research how to turn off Plymouth's splash screen entirely in order to track this down...
