microk8s not running after installation

Question

I want to install kubeflow using microk8s on kubernetes cluster, but I faced a problem with microk8s. I already install microk8s using this link. So, when I tried to see the status on microk8s, it was said not running

microk8s is not running. Use microk8s inspect for a deeper inspection.

When I try to inspect it, and it was said like this

How you installed microk8s, please add information about your system. Have you used any installation guide? — Andrew Skorkin, Nov 23 '21 at 16:22
@AndrewSkorkin Yeah sure, I've installed the microk8s, and I use this guide installation [link](https://microk8s.io/). What did you mean about the system ? my ubuntu spec? I used GCP VM with spec 4vCPU and 16 GB with storage 60 GB (Both on Master & Worker node) — MADFROST, Nov 24 '21 at 01:18
Yes, under the system I mean a description of the system where you try to install microk8s. Under your link is the main page of microk8s site. I don't see a guide on it. Also from your comment, you want to run microk8s on a master and one worker nodes, am I right? — Andrew Skorkin, Nov 24 '21 at 13:31

Seems like the microk8s service is not running but the microk8s inspect reports that it's running. You can try to reset it using:

% sudo microk8s reset
