Root Cause Analysis 🔍

Failed to authenticate with GitHub via OctoSTS service - the authentication endpoint returned a 404 error when trying to get a token for chainguard-dev/iamguarded-tools repository as elastic-build identity. This suggests either the OctoSTS service is unavailable, the repository doesn't exist, or the elastic-build identity lacks proper permissions.

Analysis

The similar fixed build failures show a pattern where the 404 errors from GitHub authentication via OctoSTS were resolved through version updates rather than authentication fixes. In Fix Example #0, the solution was updating envoy from version 1.35.5 to 1.35.6 with a corresponding commit hash update. In Fix Example #1, the fix was incrementing the epoch for prometheus-operator due to CVE-2025-47907. Both fixes suggest that the 404 authentication errors were transient issues that resolved themselves when the build was retried with updated package metadata, rather than requiring changes to the authentication mechanism itself.

Explanation

Based on the analysis of similar fixes, the 404 authentication errors with GitHub via OctoSTS appear to be transient issues that resolve when the build is retried with updated package metadata. The pattern shows that version updates trigger fresh builds that bypass the authentication problems. Updating cassandra from 5.0.6 to 5.0.7 (if available) would align with Wolfi's principle of keeping packages up to date and would likely resolve the authentication issue by forcing a clean rebuild. The git-checkout step would fetch from a different commit, potentially avoiding any cached or stale authentication tokens. This approach follows the successful pattern from the envoy fix where a version bump resolved identical 404 errors.

Alternative Approaches

• Increment the epoch value (e.g., from 3 to 4) to force a rebuild without changing the upstream version, similar to the prometheus-operator fix
• Temporarily disable the iamguarded-compat subpackage that's causing the authentication failure until the OctoSTS service issue is resolved
• Check if there's a newer commit on the cassandra-5.0.6 tag that might resolve authentication issues and update the expected-commit hash
• Contact infrastructure team to verify if the 'elastic-build' identity has proper permissions for the 'chainguard-dev/iamguarded-tools' repository
