Ubuntu 18.04 hanging on halt...

Whenever I initiate `sudo halt` in Ubuntu 18.04 I usually am met with the never ending purple shutdown screen.

Any idea as to what could be done to stop this and allow the system to shutdown properly?
You can usually press the Escape key to see log output behind the plymouth screen.

Any reason for using 'halt' though? Why not poweroff/shutdown?
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".

AFAIK that is what 'halt' is supposed to do?

What do you mean with 'poweroff' not working reliably? If a 'poweroff' doesn't shut the machine down, there is something else wrong with your VM...
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...
