[Cialug] Hosed Virtualbox Install - Looking for suggestions

[c]

Posted this on the virtualbox forums, but thought I would try here in case
anyone has an idea.

I have completely hosed my virtualbox install. I am trying to completely
uninstall it so I can then install and get it working again. This is
running on ubuntu 16.04 with mate for the desktop.

I uninstalled the 5.0 virtualbox with apt-get remove. I tried to install
virtualbox 5.1 series using dpkg. As soon as I installed 5.1, I got the an
error that I couldn't start any of my VMs and to recompile the kernel. That
didn't work. So I thought I would just uninstall 5.1 and try to return to
5.0 that used to work. I cannot seem to unisntall virtualbox now

I have the following installed on my system:
- virtualbox-5.1 5.1.8-111374~U 5.1.8-111374~U
- virtualbox-ext-pack 5.0.24-0ubuntu 5.0.24-0ubuntu


When I try to uninstall I get following error message
                                                                         │
  │ Running VMs found
 │
  │
 │
  │ VirtualBox is currently running. Please close it and try again. Please
  │
  │ note that it can take up to ten seconds for VirtualBox (in particular
 │
  │ the VBoxSVC daemon) to finish running.

But I ps and grep or pgrep and there are no virtualbox processes running
before I start the remove.

When I click ok, I return to terminal with this output:
