Steps to reproduce the issue:

1.install latest version of minikube
I Installed into Ubuntu 18.04.3 LTS
amd64 / x86_64
Binary download
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube

run kubectl config view
get error :
kubectl config view
error: converting to : type names don't match (Unknown, RawExtension), and no conversion 'func (runtime.Unknown, runtime.RawExtension) error' registered.

Full output of failed command:

error: converting to : type names don't match (Unknown, RawExtension), and no conversion 'func (runtime.Unknown, runtime.RawExtension) error' registered.

Full output of minikube start command used, if not already included:

❗ /usr/local/bin/kubectl is version 1.16.0, which may have incompatibilites with Kubernetes 1.20.2.
▪ Want kubectl v1.20.2? Try 'minikube kubectl -- get pods -A'
🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

I am see this error too.

My suspicion, based on the error message, is that this may be caused by new annotations minikube adds to the KUBECONFIG file. It may be that your version of kubectl (v1.16.0) is too old to accept them.

Here is the PR that added this feature to minikube 1.17.x: #10126

tejal29 · 2021-03-17T18:25:19Z

My kubectl version is

kubectl version

WORKAROUND:
After updating kubectl to version v1.17+. i was able to switch context after creating a minikube cluster.

➜  skaffold git:(fix_container_str) ✗ kubectl version

This is why we include "minikube kubectl", to get a version that matches the cluster.

I have a Mac OS system
I had the same problem above but with kubens

_> kubectl config view
error: converting to : type names don't match (Unknown, RawExtension), and no conversion 'func (runtime.Unknown, runtime.RawExtension) error' registered.

to fix the issue use the following

You may have to delete kubectl if it is > v17 and already exists

_> rm '/usr/local/bin/kubectl'
_> brew install kubernetes-cli
_> brew link kubernetes-cli

yogendradabi3 · 2021-05-21T10:21:49Z

brew upgrade kubernetes-cli worked for me

@JakeAtTurner Thank you! This works for me.

We actually warn when the installed version of kubectl on the host doesn't match the version of kubernetes installed by minikube. Using minikube kubectl or upgrading your installed version of kubectl is the answer here.

ozanyldzgithuboffical · 2021-11-07T21:43:33Z

Deleting config and delete/start minikube by re-installing cluster is not working.

The solution is that you need to install compatible version of kubectl.exe to your installed kubernetes version.on your mini-kube. I have v1.24.0 kubernetes and I use v1.22.0 kubectl.exe . Now it is working successfully.

vrajannagari · 2022-01-20T20:23:55Z

Following worked for me for a similar issue.

rm '/usr/local/bin/kubectl'
brew install kubernetes-cli
brew link kubernetes-cli
