Tried to clone the repository and avter providing my credentials for github i get:
"
fatal: repository 'https://github.com/kubernetes-incubator/metrics-server.md/' not found
"
Also tried to go directly to the URL but recieved a 404.

Is the Repository down?

    The old url (https://github.com/kubernetes-incubator/metrics-server.git) of the metrics-server repository is still working but the course material can perhaps be updated to using the new url (https://github.com/kubernetes-sigs/metrics-server.git).

    This command from Exercise 13.3 - Step 3:

    "kubectl create -f \
https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.3.7/components.yaml"

    now gives me this error message:

    unable to recognize "https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.3.7/components.yaml": no matches for kind "APIService" in version "apiregistration.k8s.io/v1beta1"

    Simply following the lab exercises I am now at version:

    ient Version: version.Info{Major:"1", Minor:"23", GitVersion:"v1.23.1", GitCommit:"86ec240af8cbd1b60bcc4c03c20da9b98005b92e", GitTreeState:"clean", BuildDate:"2021-12-16T11:41:01Z", GoVersion:"go1.17.5", Compiler:"gc", Platform:"linux/amd64"}

    and the available API is

    $ kubectl api-versions 
[...]
apiregistration.k8s.io/v1

    So downloading the components.yaml file first and editing

    apiVersion: apiregistration.k8s.io/v1

    to match fixed the issue.

    Even with that change to the components.yaml, I still got this error:

    1 webhook.go:196] Failed to make webhook authorizer request: the server could not find the requested resource

    double checking the README section again:

    Compatibility Matrix
Metrics Server  Metrics API group/version   Supported Kubernetes version
0.6.x   metrics.k8s.io/v1beta1  1.19+
0.5.x   metrics.k8s.io/v1beta1  *1.8+
0.4.x   metrics.k8s.io/v1beta1  *1.8+
0.3.x   metrics.k8s.io/v1beta1  1.8-1.21

    I replaced 0.3.7 with 0.6.1

    Hi @SevenD,

    The README.md also provides the installation command for the latest metrics-server release:

    https://github.com/kubernetes-sigs/metrics-server#installation
