GitHub Actions v2.332.0 Container Jobs Fail with Permission Denied on GITHUB_ENV After Upgrade

What this error means

/__w/_temp/_runner_file_commands/set_env_XXXX: Permission denied is a GitHub Actions failure pattern reported for developers trying to fix container jobs failing with permission denied errors after upgrading github actions runner from v2.330.0 to v2.332.0, especially with non-root container users on arc/kubernetes. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue #4302 on actions/runner opened Mar 16, 2026. Upgrading ARC runners to v2.332.0 causes UID mismatches between runner and job containers. Root cause: Ubuntu 22.04→24.04 base image change (git 2.43+ stricter safe.directory) and container hooks v0.8.1 breaking workspace ownership. Blocks all container-based CI/CD with non-root users. Category: GitHub Actions (official repo).

Quick fixes

1. Confirm the exact error signature matches /__w/_temp/_runner_file_commands/set_env_XXXX: Permission denied.
2. Check the GitHub Actions account, local tool state, and provider configuration involved in the failing workflow.
3. Compare the failing environment with a known working setup, then change one configuration value at a time.

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

1. Capture the exact error message and the command, editor action, or request that triggered it.
2. Check whether the failure is account/auth, quota/rate, model/provider, local runtime, or deployment configuration.
3. Review the source evidence below and compare it with your environment.
4. Apply one change at a time and rerun the smallest failing action.
5. 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.

FAQ

What should I check first?

Start with the exact /__w/_temp/_runner_file_commands/set_env_XXXX: Permission denied text and the smallest action that reproduces it.

Can I ignore this error?

No. Treat it as a failed GitHub Actions workflow until the root cause is understood.

Is this guaranteed to have one fix?

No. The imported evidence supports the troubleshooting path above, but tool behavior can vary by account, plan, version, provider, and local configuration.

How do I know the fix worked?

Rerun the same command, editor action, or request. The fix is working when that action completes without /__w/_temp/_runner_file_commands/set_env_XXXX: Permission denied.
