I am getting this error
Please solve
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.

What is your setup info & configuration etc? without knowing about setup, i am unable to provide any advice just by error message.
as i said make sure you will be using containerd 1.6 or above and refer my repo github.com/ramanagali/k8s-cluster/tree/master/

/etc/systemd/system/kubelet.service.d/10-kubeadm.conf don't exist in my system and cluster is in ready state but sort of not usable can this be the reason ?

[@learnwithgvr]

Could be the reason... check kubelet status i.e systemctl status kubelet
