How To Install VirtualBox 5.2 on Linux Mint 19 / Linux Mint 18

VirtualBox is an open-source hypervisor application that helps you create and run guest operating systems (“virtual machines”) such as Linux and Windows under a host operating system. VirtualBox can be installed on host operating systems, including Linux, Windows, Solaris, OS X, and OpenSolaris. 

From the version 2.0 VirtualBox supports 32 and 64bit host and guest operating systems. If you want to install 64bit guests then your processor must support hardware virtualization and, of course, the host operating system must be 64bit as well.

VirtualBox is released under GPL v2 and Oracle VM VirtualBox extension pack is released under PUEL (Personal Use and Evaluation License).
