Use the latest Knoppix release to update your current installed Knoppix system.
Knoppix has always been designed to be run directly from the CD. As this chapter has shown, this can present some challenges when you want to install Knoppix to a system and particularly when you want to upgrade it. Recently, Knoppix has added an extra feature to its install tool to make even the upgrade process simpler.
With the Knoppix upgrade feature, all you need to upgrade an old install of Knoppix is the latest Knoppix release. Boot your system from the Knoppix disk and then type:
$ sudo knoppix-installer
to start the Knoppix installer. The installer will detect your installed Knoppix system, and the very first option you see will be “Update Starts the package updater.” Select that and Knoppix will prompt you for which disk to update. Choose the device that corresponds to your root partition (likely /dev/hda1 or /dev/sda1). Knoppix will set up your system behind the scenes to allow it to be updated directly from the CD and then launch the kpackage package management tool. While this program can install RPM and DEB packages as well as manage the packages that are on the system, you won’t use these options to update Knoppix; instead, click a special option: Special -> Apt:Debian -> Upgrade. A new window will appear and run through the full list of software that needs to be updated. You can monitor the progress of the update tool through this window, but for the most part you can sit back and let the tool update the system. The benefit to this method is that you can update directly from the disk and don’t have to download packages from the Internet. Plus if you haven’t updated your Knoppix since you installed it, this will minimize any trouble with package dependencies.
