KUBEADM Upgrade is failing

Hi,

I am trying to upgrade the controlplane from 1.18 to 1.19. But after downloading the packages, when I run kubeadm upgrade apply v1.19.0, I get the error that admin.conf file is not found.

I couldnt locate the file under /etc/kubernetes.

Am i missing something here?

If I should be doing the upgrade hardway, where can I see the documentation as I dont remember seeing in the training.

Did you check

$HOME/.kube/config 

if it is present
