00:01 Welcome to the spoken tutorial on Installing VirtualBox on Ubuntu Linux OS.
00:09 In this tutorial, we will learn to install VirtualBox on Ubuntu Linux 16.04 Operating System.
00:18 This tutorial is recorded using: Ubuntu Linux 16.04 OS,
00:25 VirtualBox version 5.2,
00:29 gedit text editor.
00:32 However, you may use any text editor of your choice.
00:37 Before we begin, please make sure that you are connected to the internet.
00:43 What is VirtualBox?

VirtualBox is a free and open source software for Virtualization.

00:50 It allows us to install and use multiple OS in the base machine i.e. host.
00:57 The base machine can have either Windows, Linux or MacOS.
01:03 To install an OS inside a VirtualBox, the base machine should have the following configuration.
01:11 i3 processor or higher,
01:14 Ram 4GB or higher,
01:17 Hard disk free space 50GB or more and
01:22 Virtualization should be enabled on BIOS.
01:27 This will ensure that the VirtualBox will work smoothly.
01:32 In case the base machine has Ubuntu Linux OS, then it should be any one of the following versions:
01:40 Ubuntu Linux 14.04, Ubuntu Linux 16.04 or Ubuntu Linux 18.04.
01:50 Let us start the installation.
01:53 The commands used in this tutorial are available in the Code Files link, below the player.
02:00 I have opened this file in gedit text editor on my machine.
02:05 And, I will use the same file to copy-paste the commands during the demonstration.
02:11 Important note: Before installing VirtualBox, we have to ensure that Virtualization is enabled on our machine.
02:21 Let us verify if Virtualization is enabled or not.
02:26 Open the terminal by pressing Ctrl, Alt and T keys simultaneously on your keyboard.
02:35 Copy this command from the code file and paste it in the terminal.

Press Enter to execute.

02:43 If the output has vmx flags then Virtualization is enabled on this computer.
02:50 If it is not enabled, kindly enable it in BIOS settings.
02:55 As the BIOS settings vary from computer to computer, we cannot show a demo of the same.
03:02 If you are not a technical person, kindly do this with the help of a System Administrator.
03:09 If the option Virtualization is not available in the BIOS then we cannot install VirtualBox in that machine.
03:17 In my case, it is already enabled.
03:21 First, let us update the base machine with the help of the following command.
03:27 For that, on the terminal, type: sudo <space> apt-get <space> update

Then press Enter.

03:38 You may be prompted to enter your system password.

Type the password and press Enter.

03:46 From now on, type the system password whenever prompted, during this installation and press Enter.
03:55 Next let us install VirtualBox.

Now we have to add the VirtualBox repository to the Ubuntu source list.

04:04 To do so, copy this command and paste on the terminal.

Then press Enter.

04:11 Next, we have to add the VirtualBox repository key to the apt source.
04:17 To do so, copy these two commands one by one.

Paste them on the terminal and press Enter.

04:32 Now, we have to update the repository list.
04:36 For that, type on the terminal, sudo <space> apt-get <space> update

Then press Enter.

04:50 Next, type: sudo space apt-get space install space virtualbox-5.2

And press Enter.

05:04 The terminal will display the list of packages to be installed,
05:09 file size to be downloaded from the internet and the disk space usage after the installation.
05:17 When asked, “Do you want to continue?”, type Y and then press Enter.
05:23 The installation may take some time depending on your internet speed.
05:31 The installation is completed now.
05:34 Now, go to Dash home. In the search bar, type Virtualbox.
05:42 Now double-click on the Oracle VM VirtualBox icon.
05:47 VirtualBox application opens. This indicates that the installation is successful.
05:54 With this, we come to the end of this tutorial.

Let us summarize.

05:59 In this tutorial, we have learnt to: check if Virtualization is enabled and

install VirtualBox in Ubuntu Linux 16.04 OS.
