How Do I Install Guest Additions in a Virtualbox Vm?

I've recently installed Ubuntu on Oracle's Virtualbox. Now I want to install the guest additions.

I started up my Ubuntu guest OS, clicked "Devices" and chose "Install Guest Additions". Nothing happened, and I don't see the CD icon on my desktop.

How can I make this work?

If you have trouble installing Ubuntu in a VirtualBox VM, because the installer window does not fit the low resolution screen size, you can move the window with Alt+F7.

Installing Guest additions from the repositories

In case we have installed the OSE edition of Virtual Box from the repositories we can add the guest additions from the repositories in the guest. This will install guest additions matching the Virtual Box version as obtained from the repositories. It is not recommended to install these in newer releases of Virtual Box as obtained from the Oracle repository (see below).

Alternatively we can install the package virtualbox-guest-additions-iso in the host Ubuntu.

sudo apt-get install virtualbox-guest-additions-iso

The .iso file with an image of the OSE edition of the guest additions CD will install in the host directory /usr/share/virtualbox/VBoxGuestAdditions.iso. Mount this .iso file as a CD in your virtual machine's settings. In the guest you will then have access to a CD-ROM with the installer.
