Setting Up Puppeteer Sandbox on Linux: Encountering Sandbox Issues

I recently set up Puppeteer for generating PDFs and thumbnails, but I’m having trouble activating the Chrome Sandbox on my Linux system. I keep receiving the following error message:

(node:46) UnhandledPromiseRejectionWarning: Error: Could not launch chrome!
[1208/055442.253403:FATAL:zygote_host_impl_linux.cc(116)] No usable sandbox! Please update your kernel or refer to the documentation on SUID sandbox development for guidance. If you’re looking for a quick fix, you might consider running with --no-sandbox.

I’ve tried following the official setup instructions, but I still can’t get it to work. Here’s the command sequence I used:

# Navigate to the Puppeteer Chromium directory
cd <project-directory>/node_modules/puppeteer/.local-chromium/linux-<revision>/chrome-linux/

# Change ownership and permissions for the sandbox
sudo chown root:root chrome_sandbox
sudo chmod 4755 chrome_sandbox

# Copy the sandbox executable to a global location
sudo cp -p chrome_sandbox /usr/local/sbin/chrome-dev-sandbox

# Set the environment variable for the sandbox
export CHROME_DEV_SAND_BOX=/usr/local/sbin/chrome-dev-sandbox

When setting up the Chrome sandbox, ensure that your kernel supports user namespaces as it is essential for the sandbox to function correctly. If your distribution’s kernel lacks this support, you may need to either recompile your kernel with CONFIG_USER_NS enabled or upgrade to a distribution that includes this support out-of-the-box. Additionally, verify that no conflicting permissions or security settings are enforced on your system, which might prevent the sandbox from becoming operational, such as SELinux or AppArmor policies.

sometimes, switching from using built-in chromium to a separately-installed system chromium helps resolve sandbox-related problems. just edit your puppeteer script to point to your local chromium installation. don’t forget to check for any specific dependency missing in your linux environment that might affect chromium’s functioning.

another solution might be to make sure that the full path of ur sandbox executable is available when puppeteer is running. sometimes relative paths can cause issues, double check that ur CHROME_DEV_SANDBOX environment variable has the correct absolute path to sandbox on ur machine. good luck!
