Ubuntu 13.04 – How to Uninstall VirtualBox Guest Additions

These instructions are for removing VirtualBox Guest Additions from Ubuntu 13.04 running under VirtualBox version 4.2.12.

They may be the same or similar for other version combinations and other Linux distros, but no guarantee is made.

cd /media
cd <username>
cd VBOXADDITIONS_4.2.2_81494
sudo sh VBoxLinuxAdditions.run uninstall

Note: <username> is the name of the user who installed the VirtualBox Guest Additions. Note: Ubuntu makes it difficult (but not impossible) for someone other than the original installer to uninstall the VirtualBox Guest Additions. I am not covering how to do that here.

VBOXADDITIONS_4.2.12_84980 is the version of VirtualBox Guest Additions installed. The way I enter it is to: (1) type cd VB, then (2) press the Tab key to auto-complete the name

After entering your password, the VirtualBox Guest Additions will be uninstalled:

1) Click on the Files icon on the Unity Launcher:

2) Click on the Eject icon next to the Guest Additions:
