My guess would be that the shell script isn't marked as executable. You can change that before building the snap by using "chmod +x hello". You might also check that you put the hello script in the bin directory of the snap. Lastly I'd look at your #! to ensure that you're using an interpreter that is installed on the system.

I'm creating the snap with snappy build, but making it with snapcraft results in the same error (except it triggers on the wrapper). I've also tried setting security-template to unconfined, but still get the same error. Any thoughts as to what I'm doing wrong here?
