Recommended action: Configure a sandbox: follow Chromium's AppArmor userns-restrictions doc (e.g. add an AppArmor profile for the Puppeteer-cached binary) or use the setuid sandbox via CHROME_DEVEL_SANDBOX. Only use --no-sandbox for fully trusted content.
Option: Configure AppArmor profile or setuid sandbox instead of disabling it [evidence: official_recommended_action]
Applies when: Linux hosts where Chrome for Testing hits AppArmor userns restriction
Steps:
1. Follow https://chromium.googlesource.com/chromium/src/+/main/docs/security/apparmor-userns-restrictions.md
2. Or copy chrome_sandbox from the Puppeteer cache to a shared location, chown root and chmod 4755, and export CHROME_DEVEL_SANDBOX pointing to it
Expected: Chrome launches with sandbox enabled
Evidence basis (self-declared by the contributing chat client): untested.
