Generated `Install ripgrep` step can block the agent job indefinitely

[mnkiefer]

The generated Install ripgrep prerequisite step can block indefinitely before the agent starts. The installer uses quiet, unbounded apt-get commands, so the job provides no progress output and has no local timeout or fallback when package installation stalls.

This occurred on a GitHub-hosted ubuntu-latest runner, not a self-hosted runner.

Environment

• gh-aw: v0.86.2
• Runner: GitHub-hosted ubuntu-latest

Actual behavior

The generated step started at 07:13:04Z and produced only one installer message before it was manually cancelled at 07:19:36Z:

Install ripgrep  2026-08-19T07:13:04.1391302Z Run bash "${RUNNER_TEMP}/gh-aw/actions/install_ripgrep.sh"
Install ripgrep  2026-08-19T07:13:04.1512905Z ripgrep not found; installing with apt-get...
Install ripgrep  2026-08-19T07:19:36.6133961Z The operation was canceled.

The agent never started. Standard run cancellation also did not finish promptly; the run ultimately required the Actions force-cancel endpoint.

The installer in github/gh-aw-actions at v0.86.2, setup/sh/install_ripgrep.sh, executes:

echo "ripgrep not found; installing with apt-get..."
sudo apt-get update -qq
sudo apt-get install -y -qq ripgrep

Neither command has a timeout. The -qq option also makes it impossible to tell whether the update or install command is blocked.

Expected behavior

Generated prerequisite installation should finish within a bounded period or fail with a clear diagnostic, allowing the workflow to terminate normally instead of consuming the full job timeout before agent execution.

Same issue on my end.
