No matches for kind DaemonSet error while deploying flannel on Kubernetes

I was playing with the latest version of Kubernetes deployment on Ubuntu today. To have it fully functional Kubernetes cluster, you need to deploy a networking overlay on top. I choose to deploy flannel. When I was trying to deploy flannel, I got an error: no matches for kind DaemonSet in version extensions/v1beta1. See full message below.

Unable to recognize "https://raw.githubusercontent.com/coreos/flannel/bc79dd1505b0c8681ece4de4c0d86c5cd2643275/Documentation/kube-flannel.yml": no matches for kind "DaemonSet" in version "extensions/v1beta1"

I did start poking around the internet and I did find a post on StackOverflow with a similar issue. It turned out DaemonSet, Deployment, StatefulSet, and ReplicaSet resources will no longer be served from extensions/v1beta1, apps/v1beta1, or apps/v1beta2 by default in v1.16 or later. As I was using the latest stable k8s version, I had to modify the YML file manually to make it working with my deployment.
You need to change the apiVersion section of the YML file

apiVersion: extensions/v1beta1 -> apiVersion: apps/v1

Then, there is another error

missing required field "selector" in io.k8s.api.apps.v1.DaemonSetSpec;

I have to add selector filed into kube-flannel.yml

spec:
   selector:
     matchLabels:
      tier: node
      app: flannel

Make sure you add selector section in all DaemonSet sections of yml file

apiVersion: apps/v1
 kind: DaemonSet
 metadata:
   name: kube-flannel-ds-amd64
   namespace: kube-system
   labels:
     tier: node
     app: flannel
 spec:
   selector:
     matchLabels:
      tier: node
      app: flannel
   template:
     metadata:
       labels:
         tier: node
         app: flannel

When you update yml file, you can use kubectl to deploy flannel

cloud_user@ip-10-0-1-101:~$ kubectl apply -f /home/cloud_user/kube-flannel.yml

Check if nodes are in READY state:

cloud_user@ip-10-0-1-101:~$ kubectl get nodes
