Hi, am doing the lab to upgrade the cluster using katacode. Kubernetes version in the lab is 1.18. So trying to upgrade it to 1.19.12-00 but getting the below error. Any idea how to upgrade the cluster from 1.18 to 1.19.

E: Version ‘1.19.12-00’ for ‘kubeadm’ was not found

@Subba I think when you run below command , there is list till 1.19.4 . That’s why i think you cannot upgrade to 1.19.12-00

apt-cache madison kubeadm
