How To Remove Virtualbox Guest Additions in Ubuntu

Ubuntu 1

VirtualBox Guest Additions are a set of device drivers and system applications designed to achieve closer integration between the host and guest operating systems. They help to enhance the performance of the guest operating system. However, there might be instances where you need to remove these additions from your Ubuntu system. This article will guide you through the process of removing VirtualBox Guest Additions in Ubuntu.

Quick Answer

To remove VirtualBox Guest Additions in Ubuntu, you can use the apt-get remove command to uninstall the Guest Additions package, and then run the uninstallation script to remove the vboxguest kernel module. Finally, reboot your system for the changes to take effect.

Checking the Installation of Guest Additions

Before you proceed with the uninstallation, it’s important to first verify if the Guest Additions package is installed on your system. Open your terminal and run the following command:

dpkg -l | grep virtualbox

This command lists all the packages installed on your system that contain the word “virtualbox”. If the output shows “unity-scope-virtualbox”, it means the Guest Additions package is installed.

Removing the Guest Additions Package

To remove the Guest Additions package, execute the following command in your terminal:

sudo apt-get remove unity-scope-virtualbox

This command uses the apt-get remove function to uninstall the package named “unity-scope-virtualbox”. The sudo command is used to execute the command with root privileges.

Checking the vboxguest Kernel Module

Next, you need to check if the vboxguest kernel module is loaded. This can be done by running the following command:

lsmod | grep -io vboxguest

The lsmod command shows the status of modules in the Linux Kernel. The grep -io vboxguest command filters the output to only show entries containing “vboxguest”. If the output shows “vboxguest”, it means the module is loaded.

Removing the vboxguest Kernel Module

The vboxguest kernel module can be removed by following these steps:

  1. Change into the /opt/VBoxGuestAdditions-<version_number> directory by running the following command:
cd /opt/VBoxGuestAdditions-<version_number>

Replace <version_number> with the actual version number of the VirtualBox Guest Additions installed on your system.

  1. Run the uninstallation script by executing the following command:
sudo ./uninstall.sh

This command runs the uninstallation script which removes the vboxguest kernel module from your Ubuntu system.

Rebooting the System

After removing the Guest Additions package and the vboxguest kernel module, you should reboot your Ubuntu system for the changes to take effect. This can be done by running the sudo reboot command.

Please note that removing the Guest Additions may disable some features like mouse pointer integration and screen resizing. If you encounter any issues, consider updating the VirtualBox Guest Additions to the latest version instead of removing them completely.
