This question already has an answer here:

I'm trying to install the Virtual Box extentions to add USB 2.0 functionality. While I install, a box pops up and asks for the administrative password. When I enter the password, it tells me it was incorrect and I can't install.

I only have Ubuntu installed on my laptop, and I'm the only user, so the admin password is my password.

Any help, or is this just a bug? I've got 13.04 btw.
