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.
GNOME_SUDO_PASS
Sorry, try again.
sudo: 3 incorrect password attempts.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ExtPackManager
Interface: IExtPackManager {3295e6ce-b051-47b2-9514-2c588bfe7554}

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.

1 Answer 1

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.
