How to install VirtualBox 4.3.28 on Ubuntu

Operating system virtualization is something that system administrators sometimes have to live with on a daily basis. Many times it is easier to have an alternative operating system installed inside a virtual machine on a server than to have a dual boot or even triple boots. To avoid that VirtualBox was invented.

We talk about VirtualBox and virtual machines almost always in a server environment, since that is where we most often find this type of solution. On home computers they don't make much sense, beyond testing an operating system or checking an installation, but there are still many users who use them. That is why we have decided to teach you how to install VirtualBox 4.3.28 in the latest versions of Ubuntu.

For those who do not know what VirtualBox is, it is about a fully operating system virtualization solution opensource, and also free, which is maintained by the Oracle company. It is fully multiplatform and is one of the most used virtualization programs worldwide together with VMWare.

First of all, it is worth clarifying that this version 4.3.28 it's a maintenance release no big or significant changes for the user, where most of the work done has been directed to correcting bugs that are not perceptible to the naked eye.

For install VirtualBox on Ubuntu First of all we will have to open a terminal and type the following:

gksudo gedit /etc/apt/sources.list

Then we will have to enter one of the following lines, depending on whether we use Ubuntu 15.04, Ubuntu 14.10 or Ubuntu 14.04 LTS:

#Ubuntu 15.04

deb http://download.virtualbox.org/virtualbox/debian vivid contrib

#Ubuntu 14.10

deb http://download.virtualbox.org/virtualbox/debian utopic contrib

#Ubuntu 14.04 LTS

deb http://download.virtualbox.org/virtualbox/debian trusty contrib

After having entered the one that corresponds to our version, we will have to save the file configuration of the repositories before closing it. The next thing will be to export the security key. To do this, in the terminal we enter the following command:

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add --

The next thing on the list of steps to follow is update the list of repositories and install the package:

sudo apt-get update
sudo apt-get install virtualbox-4.3

And with this We will already have VirtualBox 4.3.28 installed on our computer.
