Snap Version Update for Ubuntu 24.04 #581

Hi Team, I am using the official Ubuntu 24.04 AMI with ssm agent 3.3.131.0 pre-installed with snap. But it comes with an error:

snap.amazon-ssm-agent.amazon-ssm-agent.service - Service for snap application amazon-ssm-agent.amazon-ssm-agent

I also tried updating to the candidate version 3.3.551.0 but with the same error.

After contacting AWS Support, they advised me to use deb installation 3.3.551.0-1 and everything works fine. Given the scenario, it seems an update on Snap is needed for seamless experience on Ubuntu 24.04 EC2 instances.

How did you do the deb installation? I'm struggling to get the agent to work.

Also, is there any official support here? Or do we need to feedback on the official forum?

Attempted to reproduce with the AMI ami-0866a3c8686eaeeba, but could not reproduce:

Suspecting instance profile related issue when you see that registration is not successful, instead of Agent software issue. Did you look into changing the instance profile?
