An error occurred after the command: docker-compose up

The file affected is app.docker

E: Package 'mysql-client' has no installation candidate
ERROR:

Package mysql-client is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

To solve, edit app.docker to apt-get install default-mysql-client instead of mysql-client.
