I am creating a new docker container with ubuntu:15.04 using docker configuration file Dockerfile. The file has commands app-get upgrade and app-get update. The below error is being thrown whenever rsync, nginx or php5-fpm is being setup and container creation fails. Please let me know how can this be resolved.
invoke-rc.d: policy-rc.d denied execution of restart.
