package 
{ 'mysql-server':
  require => Exec['apt-update'],        # require 'apt-update' before installing
  ensure => installed,
}

Answer 1

When you use package resource without explicit provider Puppet tries to figure out what provider should be used based on facts.

At the start Puppet gathers facts about system, operating system and what is available to use. Based on those facts it will use provider that is most likely to work.

You can see what facts are required for every provider to work in the package documentation page: https://docs.puppet.com/puppet/latest/type.html#package-providers
