Patch Manager Prerequisites

SSM Agent Version

Version 2.0.834.0 or later of SSM Agent be running on the instances you want to manage with Patch Manager.

Note

SSM Agent is updated whenever changes are made to Systems Manager and when new capabilities are added. To ensure that your instances are always running the newest version of SSM Agent, we recommend that you create a State Manager association that automatically updates SSM Agent when a new version is available. You can also use Run Command to quickly update one or more instances with the latest version. For more information, see Automatically Update SSM Agent (CLI) (State Manager) and Update SSM Agent by using Run Command.

Supported Operating Systems

The Patch Manager capability does not support all the same operating systems versions that are supported by other AWS Systems Manager capabilities. For example, Patch Manager does not support CentOS 6.3, Raspbian Stretch, or Windows Server 2003. (For the full list of Systems Manager-supported operating systems, see Systems Manager Prerequisites.) Therefore, ensure that the instances you want to use with Patch Manager are running one of the operating systems listed in the following table.
