What does "lsmod | grep vb" tell you when run from a host terminal?

Also where do you or did you get your VirtualBox install from. Previous and now.

There was no response to lsmod | grep vb
Thank you,

OK and the second part of my question?

Oops!

Here's the line from sources.list:
deb http://download.virtualbox.org/virtualbox/debian jessie contrib

There may be some corruption in dkms or apt. If you have already removed the previous one and still get the "it is already installed" I would clean dkms and apt then see if it installs. You might also try to install by downloading the binary and using dpkg to install it.
