Hi @oophilip,
I have seen a similar behavior of the apt repos for Kubernetes reported for a cluster hosted on AWS EC2. It seems the Kubernetes repos are somehow modified after the installation and upgrade steps from the earlier labs 3 and 4, and can no longer be validated by the apt package manager.
Option #1:
Try running each command separately - first theupdate
command (even if it errors out about the Kubernetes v1.29 repo), then run theinstall
of the nfs package.Option #2 (if Option #1 does not install the nfs package):
Assuming your nodes are already on the desired Kubernetes version 1.29.1, remove the apt repository for Kubernetes and the gpg key:sudo rm /etc/apt/sources.list.d/kubernetes.list sudo rm /etc/apt/keyrings/kubernetes-apt-keyring.gpg
Then try Option #1 again.
Hope this solution will help you to move past the install step on the control plane node.
Regards,
