How do I install Brave on Linux using the terminal?

Notes on Linux Installation:

• If Brave does not start and shows an error about sandboxing, you may need to enable user namespaces. For security reasons, we do NOT recommend running with the --no-sandbox flag. For more info, see https://github.com/brave/brave-browser/issues/1986#issuecomment-445057361.
• Brave installation via Snap is no-longer officially supported. Since Snap is community-driven and Brave cannot guarantee that they are up to date with our security updates. 

Our Linux installation documentation has moved! Please see our Readthedocs page for official installation instructions.
