Direct answer

Helm sees the latest release revision as pending. Inspect release history, then roll back or remove only the failed revision when safe.

Where this error appears

Helm upgrade and rollback

Root cause

An interrupted upgrade, client timeout, failed hook, or terminated CI job may leave release metadata in pending-install, pending-upgrade, or pending-rollback.

Minimal reproduction

helm upgrade demo ./chart --wait
# interrupt the process before completion

Corrected example

helm history demo -n default
helm rollback demo <last-successful-revision> -n default

Verify the fix

helm status demo -n default && helm history demo -n default

Things to check

  • Confirm no deployment job is actually still running.
  • Avoid deleting every release Secret as the first response.
