Installing VirtualBox Guest Additions on an Ubuntu 24.04 guest machine is a crucial step for optimizing the performance and usability of your virtual environment. By completing this process, you will unlock important features such as seamless mouse integration, shared folders, clipboard sharing, and enhanced display resolution. This guide will walk you through the installation step-by-step, ensuring that your virtual machine operates smoothly and efficiently.
Before you begin, make sure you have the following prerequisites:
- An Ubuntu 24.04 guest machine running on VirtualBox.
- Administrator (sudo) access to the Ubuntu system.
- Internet connection to install necessary packages.
- VirtualBox installed on your host machine.
Step 1: Update Your Ubuntu System
Start by ensuring that your Ubuntu 24.04 guest machine is up to date. Open your terminal by pressing Ctrl + Alt + T or searching for “Terminal” in the applications menu. In the terminal, run the following commands to update your package list and upgrade any installed packages:
sudo apt update && sudo apt upgrade -y
Step 2: Install Required Dependencies
VirtualBox Guest Additions requires certain dependencies to be installed on your system. To install these, run the following command in the terminal:
sudo apt install build-essential dkms linux-headers-$(uname -r)
This command installs essential tools, kernel headers, and DKMS (Dynamic Kernel Module Support) necessary for building the Guest Additions modules.
Step 3: Mount the VirtualBox Guest Additions ISO
Next, you need to mount the VirtualBox Guest Additions ISO. In the VirtualBox menu at the top of your guest machine window, click on Devices and then select Insert Guest Additions CD Image. This action mounts the ISO file inside your virtual machine.
Step 4: Run the Installation Script
Once the ISO is mounted, open the mounted folder, and in the terminal, run the following command to list its contents:
ls
Next, execute the installer script. You may need to enter your password when prompted. This initiates the installation process for the Guest Additions:
sudo sh ./VBoxLinuxAdditions.run
Step 5: Reboot Your Ubuntu Guest Machine
After the installation is complete, reboot your Ubuntu guest machine to apply the changes. You can do this by running the following command:
sudo reboot
Once your machine restarts, you should notice that features like screen resizing, clipboard sharing, and drag-and-drop functionality between your host and guest machines are now operational.
Extra Tips & Common Issues
If you encounter issues during installation, ensure that:
- Your VirtualBox is updated to the latest version.
