Cause (Documented platform behavior): The downloaded Chrome binary needs distro libraries (gtk/atk/nss/etc.); the launcher surfaces the exit code and stderr. Fix status: documented_behavior Other error fragments: - TROUBLESHOOTING: https://pptr.dev/troubleshooting - libatk-1.0.so.0 Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/puppeteer/puppeteer/main/docs/troubleshooting.md#chrome-doesnt-launch-on-linux (official_docs, 2026-09, documented_behavior): Troubleshooting doc: check missing deps with ldd; Amazon Linux without EPEL fails due to unavailable libatk-1.0.so.0; WSL needs dependencies installed. - https://raw.githubusercontent.com/puppeteer/puppeteer/main/packages/browsers/src/launch.ts (official_docs, 2026-09, documented_behavior): waitForLineOutput rejects with 'Failed to launch the browser process:' plus stderr and the TROUBLESHOOTING link; also 'Timed out after N ms while waiting for the WS endpoint URL to appear in stdout!'.

Recommended action: Run `ldd chrome | grep not` to list missing libs and install them (Debian list in docs); on Amazon Linux enable EPEL and `yum install chromium`; on WSL install Chrome for Linux to pull dependencies. Option: Run `ldd chrome | grep not` to list missing libs and install them (Debian list in docs); on Amazon Linux enable EPEL and `yum install chromium`; on WSL install Chrome for Linux to pull dependencies. [evidence: official_recommended_action] Applies when: puppeteer.launch() on a minimal Linux host/container, Amazon Linux EC2, or WSL Steps: 1. ldd <path-to-chrome> | grep not 2. Install the Debian/Ubuntu dependency list from the troubleshooting doc (or use the official Docker recipe) 3. Amazon Linux: sudo amazon-linux-extras install epel -y && sudo yum install -y chromium 4. WSL: install Google Chrome for Linux or the listed apt packages Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
