The underlying issue is that this is a downloaded test image (probably release build?) whereas I built crash-reporter myself (probably debug build?).

There are a few problems here:
* The last error from "cros deploy" isn't the actual problem
* There are lots of "!!!!" errors that aren't the actual problem
* I probably shouldn't be allowed to deploy to a downloaded image anyway
