either use apt-get install synaptic then select apt-file and base-config , basicly some nornal debian files are not installed but its under Base System menu in synaptic

also you could just use apt-get install apt-file base-config


This fix's the apt-setup command not being found under knoppix 3.4 hard drive install

also to fix it first you have to run apt-get update

and use like kwrite too edit your /etc/apt/sources.list file it needed

before it will install apt-file and base-config

just wanted to post this info if anyone else needed to fix the missing apt-setup message
