Installing VirtualBox Guest Additions Step-by-Step Guide

Follow these detailed steps to successfully install the Guest Additions on your Ubuntu 24.04 virtual machine.

1. Update Package IndexesStart by updating your package indexes to ensure you have access to the latest versions of packages and their dependencies.

   $ sudo apt update

   This command fetches the list of available updates from configured sources. It’s a good practice to run this command before installing new software to ensure you are getting the latest versions.

2. Install Prerequisites: Before installing Guest Additions, certain prerequisite packages must be installed.

   $ sudo apt install build-essential dkms linux-headers-$(uname -r)

   This command installs the required packages for building kernel modules, including the headers for your current kernel version. ‘dkms’ ensures that the Guest Additions kernel modules are properly updated when the kernel is updated.

3. Insert Guest Additions CD Image: Next, you need to insert the VirtualBox Guest Additions CD image into your virtual machine.

   

   

   This step usually involves selecting the ‘Insert Guest Additions CD image’ option from the VirtualBox menu. Once inserted, the CD image will appear on your Ubuntu desktop.

4. Run Autorun Script: Navigate to the CD image and run the autorun script by right click on autorun.sh > Run as a program

   

   This will start the Guest Additions installation process. You might need to enter your administrative password to proceed.
