Apt (Advanced Package Tool) is a package manager available on Debian, Ubuntu, and several other operating systems. The apt module provides a series of classes, defines, types, and facts to help you automate Apt package management.
**Note**: For this module to correctly autodetect which version of Debian/Ubuntu (or derivative) you're running, you need to make sure the 'lsb-release' package is installed. We highly recommend you either make this part of your provisioning layer, if you run many Debian or derivative systems, or ensure that you have Facter 2.2.0 or later installed, which will pull this dependency in for you.
**Note:** Setting the apt module's `purge_sources_list` and `purge_sources_list_d` parameters to 'true' will destroy any existing content that you haven't declared through Puppet. The default for these parameters is 'false'.
**Warning:** Using short key IDs presents a serious security issue, potentially leaving you open to collision attacks. We recommend you always use full fingerprints to identify your GPG keys. This module allows short keys, but issues a security warning if you use them.
By default, the `apt::backports` class drops a pin file for backports, pinning it to a priority of 200. This is lower than the normal default of 500, so packages with `ensure => latest` don't get upgraded from backports without your explicit permission.
If you raise the priority through the `pin` parameter to 500, normal policy goes into effect and Apt installs or upgrades to the newest version. This means that if a package is available from backports, it and its dependencies are pulled in from backports unless you explicitly set the `ensure` attribute of the `package` resource to `installed`/`present` or a specific version.
### Update the list of packages
By default, Puppet runs `apt-get update` on the first Puppet run after you include the `apt` class, and anytime `notify => Exec['apt_update']` occurs; i.e., whenever config files get updated or other relevant changes occur. If you set `update['frequency']` to 'always', the update runs on every Puppet run. You can also set `update['frequency']` to 'daily' or 'weekly':
~~~puppet
class { 'apt':
update => {
frequency => 'daily',
},
}
~~~
### Pin a specific release
~~~puppet
apt::pin { 'karmic': priority => 700 }
apt::pin { 'karmic-updates': priority => 700 }
apt::pin { 'karmic-security': priority => 700 }
~~~
You can also specify more complex pins using distribution properties:
~~~puppet
apt::pin { 'stable':
priority => -10,
originator => 'Debian',
release_version => '3.0',
component => 'main',
label => 'Debian'
}
~~~
To pin multiple packages, pass them to the `packages` parameter as an array or a space-delimited string.
### Add a PPA (Personal Package Archive) repository
~~~puppet
apt::ppa { 'ppa:drizzle-developers/ppa': }
~~~
### Add an Apt source to `/etc/apt/sources.list.d/`
~~~puppet
apt::source { 'debian_unstable':
comment => 'This is the iWeb Debian unstable mirror',

## Limitations
This module is tested and officially supported on Debian 6 and 7 and Ubuntu 10.04, 12.04, and 14.04. Testing on other platforms has been light and cannot be guaranteed.
## Development
Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can't access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.
For more information, see our [module contribution guide.](https://docs.puppetlabs.com/forge/contributing.html)
