Have you tried installing from a downloaded .deb file?

you install the opensource version of virtual box using

apt install virtualbox

if you want a different version from the one in the repo then you need to get it off orarcle's web site

https://www.virtualbox.org/

and following these instructions

I followed the tutorial here: https://www.virtualbox.org/wiki/Linux_Downloads titled "Debian-based Linux distributions"

ok so the error above means you have missing dependencies. the error you posted above lists all the ones you need to install.

also do this before you install virtualbox:

sudo apt-get install dkms

its much easier to just use the one from the debian repos. There are missing features in the open source version, you can google for those

apt install virtualbox

I just downloaded the deb file from that page instead of trying to get apt-get to work

 

downloading the deb file worked
