Run `apt-get update` before installing other packages with Puppet

Question

I\'m trying to create puppet module which automates installation of zend server CE, this is not important here, but steps are as following

1. update /etc/apt/sour

Answer 1

Package that needs updating APT lists should require Class['apt::update']

package { "zend-server-ce-php-5.2":
   ensure => "latest",
   require => Class['apt::update']
}

If you're using custom APT source, just ensure correct ordering:

Apt::Source['my_source'] 
-> Class['apt::update']
