Since July 21st 2019, MySQL 5.7 is not supported on Ubuntu Trusty (14.04) anymore. See MySQL Product Support EOL Announcements and this post in the MySQL Forums.

The current recommendation is to run your builds on Ubuntu Xenial (16.04) with the following in your .travis.yml file:

dist: xenial

services:
  - mysql

This will default to MySQL 5.7 on Xenial.

Hope this helps!
