Code review comment for lp://qastaging/~longsleep/snapcraft/snapcraft-debs-plugin

Neat, thanks! But what's the use case for this? Pointing at a PPA's deb file? Grabbing debs from Debian directly?

It seems fragile to point to a single deb on a server since when the repository gets updated, the url will be dead.

Maybe it would be better to add PPA support to the ubuntu plugin?
