Hello,

following the official tutorial for installing microk8S and enabling add-ons as described leads to this error message:

info on workstation:

  • distro: ubuntu 21.10
  • microk8s version: v1.21.1 installed through snap!

is there a way to solve this?

It is highly likely that microk8s isn’t ready yet.
Can you try microk8s status if it is up and running?

Hello indeed microk8s status reveals that it is not running, and then the microk8s inspect command reveals this output:
