Puppeteer sandbox : No usable sandbox

Question

I installed Puppeteer to use it in the generation of pdf / minuatures, but I can not activate and configure Chrome Linux Sandbox. Always the same error message :

(node:46) UnhandledPromiseRejectionWarning: Error: Failed to launch chrome! [1208/055442.253403:FATAL:zygote_host_impl_linux.cc(116)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/master/docs/linux_suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.

I followed the steps mentioned in the official documentation, but without success

# cd to the downloaded instance
cd <project-dir-path>/node_modules/puppeteer/.local-chromium/linux-<revision>/chrome-linux/
sudo chown root:root chrome_sandbox
sudo chmod 4755 chrome_sandbox
# copy sandbox executable to a shared location
sudo cp -p chrome_sandbox /usr/local/sbin/chrome-devel-sandbox
# export CHROME_DEVEL_SANDBOX env variable
export CHROME_DEVEL_SANDBOX=/usr/local/sbin/chrome-devel-sandbox

Try with

sudo sysctl -w kernel.unprivileged_userns_clone=1

It will allows you, as unprivileged user, to access the sandbox of chromium. This is temporary and active only until reboot.
