Installing Kubernetes on Ubuntu gives permission error "Error: open servers store"

I am following this tutorial to Install Kubernetes on Ubuntu: MicroK8s - Zero-ops Kubernetes for developers, edge and IoT

When I run this command I get an error:
microk8s status --wait-ready

I get this error:
Error: open servers store: open /var/snap/microk8s/3021/var/kubernetes/backend/cluster.yaml: permission denied

This is the entire output of the command:

microk8s is running
Error: open servers store: open /var/snap/microk8s/3021/var/kubernetes/backend/cluster.yaml: permission denied
