Unable to perform patch scan on Ubuntu instances

Question

I am attempting to setup Patch Manager for all my AWS instances but all my Ubuntu servers are failing on scan. 
I've checked the servers to ensure the SSM agent is installed and the service is running. 
Servers are running Ubuntu 22.04.2.

When I run a scan I receive the below output error:

/var/log/amazon/ssm/patch-baseline-operations/jmespath/visitor.py:32: SyntaxWarning: "is" with a literal. Did you mean "=="?
  if x is 0 or x is 1:

Answer

Patch Manager now supports Ubuntu Server 22.04 LTS

You can now use Patch Manager to patch Ubuntu Server 22.04 LTS nodes. Like other supported versions of Ubuntu Server, version 22.04 LTS, uses the AWS managed AWS-UbuntuDefaultPatchBaseline patch baseline.

Hello,

As of 30th March 2023, Ubuntu 22 is [not yet supported by patch manger](https://docs.aws.amazon.com/systems-manager/latest/userguide/patch-manager-prerequisites.html#supported-os), but it is support for Amazon Linux 2023.

Please follow this [link ](https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-release-history.html) for news on update regarding this

Hope this helps.
