Comment 2 for bug 1649979

FYI related to this, I did some proposed updates to pull-lp-source to expand its common functionality, which led to adding a new pull-uca-ddebs interface that allows downloading any UCA package's ddebs (if ddebs are available in the UCA LP archive). That would help even if the uca ddebs aren't hosted at ddebs.ubuntu.com. Of course, if ddebs were not built with the UCA packages, it can't pull any, so it would help only with new UCA package builds that include ddebs.

I hope to get those changes merged into ubuntu-dev-tools for the Artful cycle.
