Error Running Hello-World Image

General
1

I just installed Docker for Ubuntu 18.04 following the instructions found here. However, when attempting to run the hello-world image, I receive this error:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "process_linux.go:430: container init caused \"rootfs_linux.go:58: mounting \\\"proc\\\" to rootfs \\\"/var/lib/docker/overlay2/8bf159640ee882387f8a087ea7d089957209f97a9ff811534adb40fbc7190ca4/merged\\\" at \\\"/proc\\\" caused \\\"permission denied\\\"\"": unknown.
ERRO[0000] error waiting for container: context canceled

When I run as sudo I get the same error. I have tried giving the user write permissions for all the directories mentioned in the error but it hasn’t solved anything. I’ve also uninstalled and reinstalled multiple times to make sure I’m following the instructions properly.

Here is the result from running ‘docker info’:
