    Unfortunately, an error has occurred:
        timed out waiting for the condition

    This error is likely caused by:
        - The kubelet is not running
        - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

    If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
        - 'systemctl status kubelet'
        - 'journalctl -xeu kubelet'

    Additionally, a control plane component may have crashed or exited when started by the container runtime.
    To troubleshoot, list all containers using your preferred container runtimes CLI.

    Here is one example how you may list all Kubernetes containers running in docker:
        - 'docker ps -a | grep kube | grep -v pause'
        Once you have found the failing container, you can inspect its logs with:
        - 'docker logs CONTAINERID'

<p>i can't understand what is the problem here , it was working then i got a similar error it syas :
🐳  Preparing Kubernetes v1.20.0 on Docker 20.10.0 ...| ❌  Unable to load cached images: loading cached images: stat /home/feiz-nouri/.minikube/cache/images/gcr.io/k8s-minikube/storage-provisioner_v4: no such file or directory</p>
<p>, i uninstalled it then reinstall it but still got error.</p>
<p>can someone help me fix this</p>

<p>You can use <code>minikube delete</code> to delete the old cluster. After that start minikube using <code>minikube start</code></p>
