Merge lp:~manchicken/kubuntu-debug-installer/kubuntu-debug-installer into lp:kubuntu-debug-installer

[Michael D. Stemle, Jr.]

NOW we're ready for merging. This implements https://wiki.ubuntu.com/DebuggingProgramCrash#Debug_Symbol_Packages.

[Philip Muškovac (yofel)]

I only took a quick glance on the merge, but I think you missed the "release" repository. You have X-updates, X-security and X-proposed, but I see no place where you add X without a suffix
