```==> default: [2014-08-13T09:53:28+00:00] ERROR: resource template[/etc/apt/sources.list] is configured to notify resource execute[apt-get update] with action run, but execute[apt-get update] cannot be found in the resource collection. template[/etc/apt/sources.list] is defined in /tmp/vagrant-chef-3/chef-solo-1/cookbooks/debian/recipes/default.rb:27:in `from_file'```
