error while modifying current-context: %w

Error message

error while modifying current-context: %w

What it means

Wraps a failure from kubeconfig.UnsetCurrentContext in UnsetOp.Run. After the kubeconfig parses successfully, this error fires when the in-memory modification (clearing the current-context field) or its serialization/write-back to the kubeconfig file fails — e.g. a malformed config structure lacking expected fields or a write error — so the current-context preference remains unchanged and the unset operation aborts.

Solutions

1. Inspect the top-level keys of the kubeconfig for malformed YAML
2. Manually unset with kubectl config unset current-context as a workaround
3. Repair the kubeconfig structure and retry
