Error: The action 'Install xmllint' has timed out after 5 minutes.
```

Search the GitHub Actions workflows for the “Install xmllint” step and inspect how it runs apt-get on Ubuntu 24.04 runners. Re-run the affected workflow or its installation command, then verify that xmllint installs within the timeout and the CI job completes successfully.
