I'm not an expert on this, but to go out on a limb; I'll say that some of the above repositories does not include a "testing" component, hence apt cant verify its validity. Given that I haven't manually changed the "/etc/apt/sources.list" file, I will say that its probably a typo error by an kubuntu update developer (Most likely someone who moved from Debian to Ubuntu, because Debian guys are big on naming their repositories "stable", "unstable" and "testing"). Just to give a further clue, I had to use an "alternative" CD to install "fiesty" on this machine and I was trying to update that to "gutsy".

Problem seems to be with the inclusion of the "testing" component for the following "gutsy" repositories archive. ubuntu. com/ubuntu/ gutsy security. ubuntu. com/ubuntu/ gutsy-security security. ubuntu. com/ubuntu/ gutsy-security archive. ubuntu. com/ubuntu/ gutsy-updates archive. ubuntu. com/ubuntu/ gutsy-updates archive. ubuntu. com/ubuntu/ gutsy-backports archive. ubuntu. com/ubuntu/ gutsy-backports
