addius: I'm actually more interested in whether the mismatch between feisty and feisty-security was caused by manual editing or not; if all you did was s/edgy/feisty, then I'd still be curious as to how edgy-security had lacked "universe" as well. Had you manually edited your sources.list, perhaps adding the edgy-security line in, prior to that substitution command?
