remastering using scripts

[bart_999]

i am trying to remaster using scripts, but when i am trying to apt-get install synaptic, it comes up with an error :

package synaptic is not available but is reffered to by another package
This may mean that the package is missing, has been obsoleted or is only available by another source
E: synaptic has no installation candidate

Please help

I'm using knoppix v4.0

apt-get update
