Container runtime is not running: output: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

9/23/2019

Basically I'm trying to create a cluster with my Ubuntu machine as a master and two Raspberry PI 3 as worker nodes and deploy a trained ML algorithm on my cluster, but all I get are errors when trying to initialize the master. I've already tried to uninstall and reinstall docker and kubernetes, I've tried the kubeadl reset command and plenty other solutions.

When running journalctl -xe it seems like the error is this [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez': timed out since it's all in red, but I've provided below the full output of the commands used.

Here are the docker information in case that they are important

    Client:
     Version:           18.06.2-ce
     API version:       1.38
     Go version:        go1.10.3
     Git commit:        6d37f41
     Built:             Sun Feb 10 03:48:06 2019
     OS/Arch:           linux/amd64
     Experimental:      false
    Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

And here are the kubernetes information in case that they are important as well

kubeadm version -o=json

    "gitVersion": "v1.16.0",

    "platform": "linux/amd64"
  }
