A strace reveals that the snap uses its modified PATH to execute a non-existing juju binary. It would not be able to use the needed binary anyway due to confinement.

juju --version
2.0.2-xenial-amd64

Is this juju installed via snap? What is the output of which juju? Either way, it should probably be updated to search /snap/bin for a juju binary.
