This gadget snap doesn't cross-build

Maybe I'm dumb, but I can't seem to get this to work. I cloned the classic branch and ran this command:
snapcraft prime --target-arch=armhf

...and this is what happened...

I'm guessing there may have been some issue with the repo back in June as this currently works for me (on the classic branch at least):

$ git clone https://github.com/snapcore/pi3-gadget
$ cd pi3-gadget
$ git checkout classic
$ sudo snapcraft prime --target-arch=armhf

Ah no, my mistake - just checked my lines above: you were missing "sudo". That's the cause of the error you saw (unfortunately root is required for the multiverse hack).
