I'm trying to find the original, unmodified /etc/apt/sources.list file for Kubuntu 12.04 (or Ubuntu 12.04). I'm referring to the one that is found in a newly-installed system. I've found lots of information on how to modify the file, but nothing on where to find the virgin version of it. It doesn't seem to be in any package.
And I'm curious: what agent is responsible for creating that original file?
The source list generator is neat and does solve the problem, but it doesn't quite answer my question. The original sources.list that somehow got onto my system included a bunch of comments which aren't in the generated list. And I'm still wondering where the list that appears in a newly installed system comes from, since it doesn't appear to be in any package.

I'm so not familiar with the Ubuntu installer, but at least on Debian the initial /etc/apt/sources.list is generated during the install process by apt-setup. It is probably something similar in Ubuntu, but to be sure you'd need to poke around in the installer code.
The commented version is the one I was looking for
@vtel57, the commented version is precisely the one I was asking about. So apt-setup does the deed during installation. That's plausible!! Interestingly, apt-setup isn't in Synaptic's package list for Kubuntu.
