error deleting cluster%q: %v

Error message

error deleting cluster%q: %v

What it means

The final delete of the Cluster object itself failed with a non-NotFound error after keysets and instance groups were cleaned up; the API server rejected or failed the delete call. (The message has a known formatting quirk: a missing space before %q.)

Solutions

1. Check the wrapped API error (conflict, RBAC, timeout)
2. Retry the delete operation
3. Remove the cluster object manually via kubectl if it persists
