What happened?

On creation of the cluster, I get the error Error: error detecting local IP: lookup localhost: Try again. I already disabled the network-resolved stub. So in the /etc/resolv.conf is the correct nameserver.

nameserver 192.168.1.1
search .

Steps to reproduce

  1. Create a k0sctl.yaml 
    apiVersion: k0sctl.k0sproject.io/v1beta1
kind: Cluster
metadata:
name: home-k0s-cluster
spec:
hosts:
- ssh:
  address: 192.168.1.190
  user: root
  port: 22
  keyPath: ~/.ssh/id_rsa
role: controller+worker
- ssh:
  address: 192.168.1.191
  user: root
  port: 22
  keyPath: ~/.ssh/id_rsa
role: controller+worker
k0s:
version: 1.24.4+k0s.0
dynamicConfig: false
  2. Run k0sctl apply --config k0sctl.yaml

Looks like is a problem of systemd-networkd when polkit is not installed. Then the /etc/hosts is not filled with the hostname.

After installation polkit the error with " Could not set hostname: Access denied" is gone.

I also edit manuell the /etc/hosts.

Know it is working.
