Looks to me like etcd process is not running, therefore you have probably made a mistake during the installation of it.

Some things to try

  1. Check if it is actually installed
    sudo systemctl cat etcd
  2. If so, is it running?
    sudo systemctl status etcd
  3. Try starting it
    sudo systemctl start etcd
    then recheck the status
  4. If it still didn’t start, then why?
    sudo journalctl -u etcd

Either way, with KTHW, if you’ve made a mistake in an earlier lab, you will often have to reset it all and start over. Nobody said it’s easy. Clue’s in the name :wink:
