Hmm, Unity 8 run, I see an attempt to start the apps i the log, but no log file... possibly a confinement issue.
There was an issue with the cgroup manager process not starting before 16.04 was initially released. Try installing the package libpam-cgfs and logging out and back in (which is required to get in to Unity 8 anyway) and see if that resolves the problem.
