I am using Ubuntu 16.04 64-bit. I was trying to uninstall VirtualBox, but I got a lot of errors which ended with a warning telling me that my Software Centre has failed. I restarted the system and was going to try again. I ran: apt-get update and apt-get upgrade before trying anything else.
When I ran the upgrade command, the VirtualBox automatically got installed along with it, but after throwing a lot of warnings at me (I don't remember exactly what those were).
I think I should uninstall this and start fresh but when I try to uninstall using apt-get remove virtualbox* --purge, I got these results:

It is telling me that it is unable to install anything because nothing has been installed, however I am able to open VirtualBox so it must be installed. I am apprehensive about trying it out in this form.
How do I uninstall this? Or should I try to use this as it is?
sudo dpkg -l | grep virtualbox- then, if installed, remove it with e.g.sudo apt-get purge virtualbox-5.1:i386.dpkg -l *virtualbox* | grep ii, as this would catch more, ie:virtualbox-5.1.22, etc. and only show installed packages.
