A series of easy and simple steps needs to be followed for the installation of Virtual-Box on our Ubuntu 14.04 LTS. The foremost reason behind installation of Virtual-box is the difficulty of having so many systems to work on the different topologies mentioned in the different experiments we performed. So, here are a few basic steps required for installation :
Step 1: Add Virtual-Box repository link in apt source list . We will edit /etc/apt/sources.list file.
sudo gedit /etc/apt/sources.list
Now paste below given lines at the end of file /etc/apt/sources.list . And save the file.
