If your CI/CD pipelines suddenly started failing out of nowhere with this error:

"error downloading Terraform: unable to verify checksums signature: openpgp: key expired"

and you’re using Databricks CLI - you’re probably hitting the same issue I did.

The Databricks CLI needs to be upgraded. Databricks released patched CLI versions after an expired verification key started breaking bundle deploy commands in CI/CD environments.

Hopefully this saves someone else some troubleshooting time.
