APT lists

Used by Debian-like Linux distros, will get configured under guest's /var/lib/apt/lists.

As explained on Wikipedia, /var/lib/apt/lists is the "storage area for state information for each package resource specified in sources.list". By enabling this bucket, apt will be able to install cached packages without hitting the remote repositories for the main package lists, being particularly useful when developing offline.

To manually enable it:

Vagrant.configure("2") do |config|
  config.vm.box = 'some-debian-box'
  config.cache.enable :apt_lists
end
