I have Knoppix running on my old Toshiba Portege 7020CT, from the DVD drive in the docking station. In order to play any videos, I am trying to install the correct video drivers, which I believe I have located, but when I go to install them, I get the following:

<esktop/xfree86-driver-neomagic-4.4.0-63152U10_5cl.i386.rpm';echo RESULT=$?
warning: ///media/hda2/home/knoppix/Desktop/xfree86-driver-neomagic-4.4.0-63152U10_5cl.i386.rpm: Header V3 DSA signature: NOKEY, key ID 99807190

Now, from this I do understand that there are some dependencies not being satisfied, but what I don't know (and would like to) is how to install these needed files. Any thoughts? Apologies if this has been posted before. I DID look, but didn't find it. Any help would be GREATLY appreciated. Thanks in advance.
