-#### apt
-
-* `always_apt_update`: Set to 'true' to update Apt on every run. This setting is intended for development environments where package updates are frequent. Defaults to 'false'.
-* `apt_update_frequency`: Sets the run frequency for `apt-get update`. Defaults to 'reluctantly'. Accepts the following values:
- * 'always': Runs update at every Puppet run.
- * 'daily': Runs update daily; that is, `apt-get update` runs if the value of `apt_update_last_success` is less than current epoch time - 86400. If the exec resource `apt_update` is notified, `apt-get update` runs regardless of this value.
- * 'weekly': Runs update weekly; that is, `apt-get update` runs if the value of `apt_update_last_success` is less than current epoch time - 604800. If the exec resource `apt_update` is notified, `apt-get update` runs regardless of this value.
- * 'reluctantly': Only runs `apt-get update` if the exec resource `apt_update` is notified. This is the default setting.
-* `disable_keys`: Disables the requirement for all packages to be signed.
-* `proxy_host`: Configures a proxy host and stores the configuration in /etc/apt/apt.conf.d/01proxy.
-* `proxy_port`: Configures a proxy port and stores the configuration in /etc/apt/apt.conf.d/01proxy.
-* `purge_sources_list`: If set to 'true', Puppet purges all unmanaged entries from sources.list. Accepts 'true' or 'false'. Defaults to 'false'.
-* `purge_sources_list_d`: If set to 'true', Puppet purges all unmanaged entries from sources.list.d. Accepts 'true' or 'false'. Defaults to 'false'.
-* `update_timeout`: Overrides the exec timeout in seconds for `apt-get update`. Defaults to exec default (300).
-* `update_tries`: Sets how many times to attempt running `apt-get update`. Use this to work around transient DNS and HTTP errors. By default, the command runs only once.
-* `sources`: Passes a hash to create_resource to make new `apt::source` resources.
-* `fancy_progress`: Enables fancy progress bars for apt. Accepts 'true', 'false'. Defaults to 'false'.
-
-####apt::unattended_upgrades
-
-* `origins`: The repositories from which to automatically upgrade included packages.
-* `blacklist`: A list of packages to **not** automatically upgrade.
-* `update`: How often, in days, to run `apt-get update`.
-* `download`: How often, in days, to run `apt-get upgrade --download-only`.
-* `upgrade`: How often, in days, to upgrade packages included in the origins list.
-* `autoclean`: How often, in days, to run `apt-get autoclean`.
-* `randomsleep`: How long, in seconds, to randomly wait before applying upgrades.

-### Testing
-
-The apt module is mostly a collection of defined resource types, which provide reusable logic for managing Apt. It provides smoke tests for testing functionality on a target system, as well as spec tests for checking a compiled catalog against an expected set of resources.
-
-#### Example Test
-
-This test sets up a Puppet Labs Apt repository. Start by creating a new smoke test, called puppetlabs-apt.pp, in the apt module's test folder. In this test, declare a single resource representing the Puppet Labs Apt source and GPG key:
-
-```
-apt::source { 'puppetlabs':
- location => 'http://apt.puppetlabs.com',
- repos => 'main',
- key => '1054B7A24BD6EC30',
- key_server => 'pgp.mit.edu',
-}
-```
-
-This resource creates an Apt source named puppetlabs and gives Puppet information about the repository's location and the key used to sign its packages. Puppet leverages Facter to determine the appropriate release, but you can set this directly by adding the release type.
-
-Check your smoke test for syntax errors:
-
-`$ puppet parser validate tests/puppetlabs-apt.pp`
-
-If you receive no output from that command, it means nothing is wrong. Then, apply the code:
-
-```
-$ puppet apply --verbose tests/puppetlabs-apt.pp
-notice: /Stage[main]//Apt::Source[puppetlabs]/File[puppetlabs.list]/ensure: defined content as '{md5}3be1da4923fb910f1102a233b77e982e'
-info: /Stage[main]//Apt::Source[puppetlabs]/File[puppetlabs.list]: Scheduling refresh of Exec[puppetlabs apt update]
-notice: /Stage[main]//Apt::Source[puppetlabs]/Exec[puppetlabs apt update]: Triggered 'refresh' from 1 events>
-```
-
-The above example uses a smoke test to lay out a resource declaration and apply it on your system. In production, you might want to declare your Apt sources inside the classes where they’re needed.
