Using Docker

I am trying to use docker following this tutorial but when I start the container I get this error.

Unable to complete request

400 Client Error: Bad Request ("failed to create shim: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: rootfs_linux.go:76: mounting "proc" to rootfs at "/proc" caused: mount through procfd: permission denied: unknown")

Is there a way to solve this?
