I have this travis build
https://travis-ci.org/emeraldjava/spring-social-yammer/builds/191685784
which started failing with this error today
This job is running on container-based infrastructure, which does not allow use of 'sudo', setuid and setguid executables.
If you require sudo, add 'sudo: required' to your .travis.yml
See https://docs.travis-ci.com/user/workers/container-based-infrastructure/ for details.
