Root Cause Analysis 🔍

Network request to OctoSTS service failed with HTTP 404 error while attempting to authenticate for GitHub access. The service endpoint 'http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/identity?audience=octo-sts.dev' returned a 404 Not Found error, indicating either the service is unavailable or the endpoint URL is incorrect.

Increment epoch from 0 to 1 to trigger rebuild with fresh authentication context

Analysis

All three similar fixes show an identical pattern: when build failures occur due to curl 404 errors from OctoSTS authentication services, the solution was to increment the epoch value in the package metadata and add a CVE reference comment. This suggests that the OctoSTS authentication issues are typically resolved by triggering a rebuild with updated package metadata, likely because the authentication service endpoints or tokens get refreshed in newer build environments.

Explanation

The fix works by incrementing the package epoch, which forces a complete rebuild in a fresh environment. This addresses the OctoSTS authentication 404 error because: 1) The ephemeral build environment will be recreated with potentially updated authentication service endpoints, 2) Any cached or stale authentication tokens that might be causing the 404 will be cleared, 3) The build system will retry the authentication process from scratch, and 4) The epoch increment ensures the package manager treats this as a newer version, forcing the rebuild. Since all three similar failures were resolved using this exact approach, it's the established pattern for fixing OctoSTS 404 authentication errors in the Wolfi build system.

Alternative Approaches

• Wait for the OctoSTS service to be restored if it's a temporary service outage
• Check if the metadata service endpoint URL has changed and update build scripts accordingly
• Implement retry logic with exponential backoff in the authentication step
• Use alternative authentication methods if OctoSTS continues to be unreliable
