6 days ago Thanks Maximiliano, how unusual, are you able to ping/ssh worker-2 from the control-plane.Alternatively, are you able to open a tab using the UI to that instance.On 11 Sep 2024, at 10:58, Maximiliano Churichi @.> wrote:

Installing a k3s Kubernetes Cluster
Issue Description
Starting from a brand new lab deployment, I'm having issues to get both worker nodes set up while following the steps.
I was able to successfully configure the control plane node and the first worker node (kubectl get nodes shows both), but when I run the ssh command on the control plane to remotely setup worker-2 it gets stuck on [INFO] systemd: Starting k3s-agent
@.:~# kubectl get nodes

[INFO] systemd: Starting k3s-agentAfter waiting for a while, I've tried to CTRL+C, "Sync the lesson environment" and try again from scratch, but the error remains.
Also, I've tried to sync on the next lab step (Kubernetes Pods) with the same result:
