Installing Brave¶
Linux
NOTE: 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.
