I have remastered knoppix and everything appears to work except apt-get install fails.

Everytime i try
apt-get install somepackage
I get
E: I wasn't able to locate file for the somepackage packege. This might mean you need to manually fix this package.

This happens with every package a try to install.

I am able to run apt-get update and it reads the packeage list ok. Checking the various apt dirs and everything appears to be the same as my standard knoppix installation and remaster envrironment.

I can chroot into the remater environment and apt-get works ok but fails when i build and try from the ISO.

Any ideas??
