I installled Knoppix 6.2.1 to a 16GB USB key Following the directions posted here:
http://www.knoppix.net/wiki/Bootable_USB_Key

I set up a 1 GB Persistant Home Directory and the system is booting fine and loading my settings.

The question I have is that when I go to Preferences > Add/Remove Applications and select an application to be added I get two windows popping up.

The first says:

Enable the installation of officially supported Debian software? and I click a button that says enable.

The second says:

Granted permissions without asking for password.

This sounds all well and good except I still can't add packages. (Note: I have 10GB+ free on the USB key)

Can someone please tell me why I can't add packages and what I can do about it?

Thank you in advance for your time and advice.
