No such file or directory when running `warnet auth`

[danielabrozzoni]

I got a "No such file or directory" when running warnet auth, I think it might be linked with the fact that I didn't have a ~/.kube directory. Creating /tmp/kube and explicitly setting export KUBECONFIG=/tmp/kube/kube.yaml fixed it.
Error log:
