Possible Solution

Tracked it down to the offending line https://github.com/techno-tim/k3s-ansible/blob/master/roles/k3s_server/templates/vip.yaml.j2#L38

• I've checked the General Troubleshooting Guide

This might be an ansible version issue? Did you get the first item in #20

[bvduijn]

You're right. I had installed ansible via apt like you mentioned in your guide but because I was on ubuntu 18.04, python3 version was too low to update ansible(?)

Now installed a debian 12 machine to manage and deploy.

Install now stops on "TASK [k3s_server : Verify that all nodes actually joined (check k3s-init.service if this fails)]" Does the VIP need to exists and point to the masters for this ?
When I try the command manually I get:

sudo k3s kubectl get nodes -l "node-role.kubernetes.io/master=true" -o=jsonpath="{.items[*].metadata.name}"
The connection to the server 127.0.0.1:6443 was refused - did you specify the right host or port?
