When running sudo kubeadm init --token-ttl=0 --pod-network-cidr=10.244.0.0/16 it always fatally errors out

Expected Behaviour

This should complete the init

Current Behaviour

sudo kubeadm init --token-ttl=0 --pod-network-cidr=10.244.0.0/16
This results in a timeout and fatal errors.
Applying the timeout API patch does not help at all:
sudo sed -i 's/failureThreshold: 8/failureThreshold: 20/g' /etc/kubernetes/manifests/kube-apiserver.yaml && \ sudo sed -i 's/initialDelaySeconds: [0-9]\+/initialDelaySeconds: 360/' /etc/kubernetes/manifests/kube-apiserver.yaml

Context

I am setting up a new Raspberry Pi Master node.
This is repeatable, following this guide and always 100% results in this error.

Your Environment

R-Pi 4
SanDisk Extreme Pro 128GB

Please seek out technical support from the kubeadm maintainers on the Kubernetes Slack, if you work out a resolution feel free to send a PR. http://slack.kubernetes.io

My recommendation is clearly stated in the README - use k3s which works flawlessly on RPi and uses far fewer resources.
