mysql install candidate in doc are incorrect

In the runner script you have:

sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

This does not work and I get this error:

55 E: Package 'mysql-server' has no installation candidate
56 E: Package 'mysql-client' has no installation candidate
57 E: Package 'libmysqlclient-dev' has no installation candidate
