current-context is not set

Error message

current-context is not set

What it means

Guard error in clearNamespace (kubens/unset.go): GetCurrentContext() returned an empty string, so `kubens -u` has no context from which to reset the namespace preference back to 'default'. The unset operation requires an active context.

Solutions

1. Set an active context with `kubectx <NAME>` before running `kubens -u`
2. If unsetting the context itself, use `kubectx -u` instead
