This error message means that the kubelet service has been intentionally masked or disabled on the system. This is typically done as a security measure to prevent accidental or unauthorized changes to the Kubernetes cluster.
To resolve this issue, you will need to unmask the kubelet service by running the following command:
sudo systemctl unmask kubelet.service
Once the service has been unmasked, you should be able to restart it using the regular systemctl commands, such as:
sudo systemctl restart kubelet.service
