sudo echo foo
during Travis'install

Blog post stating "If you currently specify sudo: false in your .travis.yml, we recommend removing that configuration soon": https://blog.travis-ci.com/2018-11-19-required-linux-infrastructure-migration
I also created a PR for the Symfony docs: symfony/symfony-docs#13675
