The release of Debian has changed. Now "wheezy" is oldstable and without any support. "jessie" is stable now.
If you use "aptitude update" you'll get some error messages. To avoid this you need an extra file '/etc/apt/apt.conf' with the contentUpdate the cache of apt withCode:APT::Default-Release "jessie";I've tested it with Knoppix 7.4.2 and V7.5.Code:su aptitude update apt-key update
Never try "aptitude upgrade" or "aptitude dist-upgrade" with Knoppix!
Have a look at "Using aptitude".. now I just need to learn how to use aptitude!
