I am trying to update Oracle VM VirtualBox from version 4.2.22 to 4.3.4.3.8.

I am using ubuntu 12.04.4 LTS.

I am getting this attached "Breaks existing package' error, opening downloaded install file
with Ubuntu Software Center.

It is important that I don't lose my existing installed virtual machines.

How should I do the upgrade? How should I do installing the extension pack?

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
