This error is because the new gadget snaps that are compatible with
ubuntu-image have not yet been promoted to the stable channel; at the
moment, you must use -c edge instead to get the right version.

I don't know if there is anything blocking their promotion to the stable
channel at this point.  Michael, Oliver, can you comment?
