I'm attempting to add the Oracle VM VirtualBox Extension Pack 4.2.12 to my VirtualBox Settings. When it asks me for authorization, I enter the same password I use with Ubuntu Software Center or any other request for authorization. I get this message after 3 attempts:

Failed to install the Extension Pack /home/camraman1/Downloads/Oracle_VM_VirtualBox_Extension_Pack-4.2.12-84980.vbox-extpack.

The installer failed with exit code 1: GNOME_SUDO_PASS
Sorry, try again.
Sorry, try again.

I'm a newbie in the world of Linux. A Windows user all of my life (except a brief time with Commodore), so I'm a old guy in a young person's world. Help me out. I've read and reread the manual. Obviously there are a few steps I must have missed or just don't understand.

I've created my VM using Windows XP. I've added myself to the Vboxusers group.

My system information is listed below.

What other information do you need from me so I can begin using the VirtualBox software to it's fullest potential? Thanks in advance.

I know it is late but I have the same problem and this is a solution that works:

  1. cd to the directory of extension pack file. (for ease of access, move it first to home).

  2. run this command:

    sudo VBoxManage extpack install <tarball>

where tarball is the full name of the extension pack file. BEWARE! Do not rename the file before hand. It should start with something like Oracle_VM_* and finished with *.vbox-extpack. Type that without the * mark, and then just hit TAB.

Move the package that you are installing the following directory:

mv name package  /usr/lib/virtualbox/ExtensionPacks

Then go to the directory where you moved:

cd /usr/lib/virtualbox/ExtensionPacks

Install the package:

sudo VBoxManage extpack install name package

Why is it necessary to move the file to that specific directory? And package is not correct - it has to be the file name. Apart from that: nothing new compared with junda's answer. – guntbert Nov 7 '14 at 21:27
