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. @@ -41,11 +46,11 @@ Apt (Advanced Package Tool) is a package manager available on Debian, Ubuntu, an To use the apt module with default parameters, declare the `apt` class. -~~~puppet +```puppet include apt -~~~ +``` -**Note:** The main `apt` class is required by all other classes, types, and defines in this module.
