yes.. knoppix is a live cd... it isnt recomended to install it to hard drive... but you can still... see, if you use debian, its litually the same...

apt-get does F*** up (please excuse me french)...

this hasnt been really any help, but really telling you that your not the only one out there with this problem... also, instead of using apt-get, why dont you use wiki... its great, temporarily downloads and installs stuff...
