This is on vagrant, so it's installing from scratch on a clean system that's never had MySQL on every time.
I can see one of those warnings in your example output.Ii think the correct my.cnf file is in packaging/deb-trusty/extra/my.cnf in this repo, but I can see that contains explicit_defaults_for_timestamp, which suggests that your installation is not coming from this repo, or is using some other my.cnf file.
