Error message

${error.message} Install-state checkpoint also failed: ${checkpointError.message}

What it means

Compound failure during applyInstallPlan: the install itself failed, and the emergency attempt to refresh the bridge install-state also failed; the error chains both messages so neither failure is masked.

Solutions

1. Fix the primary error reported at the start of the message first.
2. Then repair the install-state: restore it from backup or re-run the installer to rebuild state.
3. Check disk space and permissions if the checkpoint write failed.
