Error: certificate signed by unknown authority

Problem

User gets the following error when running any kubectl command

Unable to connect to the server: x509: certificate signed by unknown authority (possibly because of “crypto/rsa: verification error” while trying to verify candidate authority certificate “kubernetes”)

Solution

This issue occurred due to certificate change probably you ran again kubeamd reset.

delete config file from your home directory and copy

rm -rf $HOME/.kube
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
