I've installed .deb file (virtualbox-5.2_5.2.8-121009~Ubuntu~xenial_amd64.deb) on uBuntu 16.04, and i tried getting 'Virtualbox.run' (as in the link https://www.virtualbox.org/manual/ch02.html#install-linux-host) but there aren't any files with that name.
How/Where can I get the script file 'VirtualBox.run'? Thanks very much.
