What this error means
ERROR: denied: permission_denied requesting ghcr.io/your-org/your-image OR unauthorized: authentication required is a GitHub Actions failure pattern reported for developers trying to fix docker image push to github container registry failing with permission denied or unauthorized errors in ci/cd pipelines. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.
Why this happens
Comprehensive 2026 article covering all root causes: missing packages: write scope, wrong GITHUB_TOKEN scope for private repos, Docker Hub secret misconfiguration, AWS ECR no basic auth credentials, and org-level package visibility issues. Covers GHCR, Docker Hub, and ECR registries. Distinct from covered 'npm ci lockfile error' and 'permission denied publickey'.

Quick fixes
- Confirm the exact error signature matches
ERROR: denied: permission_denied requesting ghcr.io/your-org/your-image OR unauthorized: authentication required. - Check the GitHub Actions account, local tool state, and provider configuration involved in the failing workflow.
- Verify the account session, API key, provider settings, and environment where the failing tool is running.
Platform/tool-specific checks
- Verify the command, editor, extension, or API client that produced the error.
- Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
- Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
Step-by-step troubleshooting
- Capture the exact error message and the command, editor action, or request that triggered it.
- Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
- Review the source evidence below and compare it with your environment.
- Apply one change at a time and rerun the smallest failing action.
- Keep the working fix documented for the team or deployment environment.
How to prevent it
- Keep provider/tool configuration documented.
- Record non-secret diagnostics such as tool version, provider name, model name, and command path.
- Add a lightweight check before CI or production workflows depend on the tool.
