Synaptic can do it but first you have to install synaptic. Kpackage can do it too.
Basic info:
Knoppix is a Debian based system which means that the programs come as .deb packages and are installed/removed with dpkg.
Download & install packages uses apt-get which will downloads the packages then uses dpkg to install it.
To select packages from a list of available packages use dselect (text only), Kpackage or Synaptic. Kpackage & Synaptic are graphic & mre user friendly than dselect. These also call apt-get which in turn calls dpkg to do the actual download & install.
Lists of available sources for packages is in the file /etc/apt/sources.list. The system maintains a database of available packages. This database must be updated before you attempt to install packages which is done with the command 'dselect update' or 'apt-get update'.
So first update your package list, then install want with 'apt-get install <package name>' or you Kpackage or Synaptic to choose & install your package.
Removal is done with 'apt-get --purge remove <package>' or 'dpkg -P <package>'. Using the --purge option means that it will also remove the configuration files for the package.
You can also remove packages with Kpackage or Synaptic.
