Comment 2 for bug 713876

It's not just the jigdo's that are wrong -- the "natty-src-3.iso" file that I downloaded from the web also includes the wrong source code (xserver-xorg-video-intel_2.13.901 rather than version 2.14).

It appears that Ubuntu is intentionally violating the GPL every time it cuts an alpha or beta release, by releasing binary CD/DVDs without matching sources. And marking this "importance: Low"? I don't think releasing matching sources for your binaries is optional, whether or not "Unfortunately, this is extremely hard to fix." If you can't fix it, you can't ship those binaries. Any GPL copyright holder could sue you over it, today, and shut down your release process.

It also seems bizarre that Ubuntu can manage to build complete binary releases but can't build matching source releases. In every other shop I've ever dealt with, the source release is built first, THEN the binaries are built from the sources. Why can't Ubuntu make releases in the normal way, which would guarantee the ability to produce matching sources and binaries?
