Ubuntu – Kubectl error: memcache.go:265] couldn’t get current server API group list: Get

I’m currently facing an issue with my Kubernetes clusters and need some assistance. Everything was running smoothly until today. However, after performing an update on my Ubuntu system, I’m unable to establish a connection from my working environment to the kubernetes clusters.

When executing the command kubectl get pods, I’m encountering the following error message:

E0805 09:59:45.750534 234576 memcache.go:265] couldn’t get current server API group list: Get "http://localhost:3334/api?timeout=32s": EOF

Here are the details of my cluster setup: Kubernetes 1.27, bare-metal, Host System is Ubuntu 20.04

I would greatly appreciate any guidance or insights on resolving this issue.

    It’s authentication issue – to API
    ensure kubeconfig exists and correct from which user command is executed.
    This usually observed during bootstrap a cluster and forget to run below
    mkdir -p $HOME/.kube
    sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
    sudo chown $(id -u):$(id -g) $HOME/.kube/config
