Thanks for the report, @vinothraj3!

We're on it, hope to deliver fix very soon.

Fixed with https://github.com/hystax/optscale/commit/31fbc893347be906ffc9d9f97a11ce965a54ffcc

Before new try, please reset existing k8s cluster

sudo kubeadm reset rm -rf ~/.kube sudo rm -rf /etc/kubernetes sudo rm -rf /var/lib/etcd/ echo "KUBELET_EXTRA_ARGS=" | sudo tee /etc/default/kubelet

Good afternoon , I did not quite understand how to solve the problem I install it through ansible so k8s_repo: "deb https://apt.kubernetes.io/ kubernetes-xenial main" And the same error comes out. Failed to update apt cache: E:The repository 'https://apt.kubernetes.io kubernetes-xenial Release' does not have a Release file. What should I do to get the installation started?

@XXXandr84, hi!

Please follow these steps:

1. Update to the latest version of OptScale
2. Reset existing k8s cluster

   sudo kubeadm reset
   rm -rf ~/.kube
   sudo rm -rf /etc/kubernetes
   sudo rm -rf /var/lib/etcd/
   echo "KUBELET_EXTRA_ARGS=" | sudo tee /etc/default/kubelet

3. Remove this file: sudo rm /etc/apt/sources.list.d/kubernetes.list

After that, please, try again!)
