Unable to create new AMI with latest SSM Agent in AWS
This issue was originally opened by @marcottedan in https://github.com/hashicorp/packer/issues/11700 and has been migrated to this repository. The original issue description is below.
Overview of the Issue
Packer not working anymore with AWS SSM Agent 3.1.1188.0 but still works with 3.1.1045.0. I get the following error:
ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain
Reproduction Steps
packer build .
Packer version
From packer version 1.8.0
Simplified Packer Template
source "amazon-ebs" "base" {
source_ami = "aws-windows-server-2019 AMI"
region = "us-east-1"
instance_type = "m5a.large"
ami_name = "packer_2019_base-{{isotime `2006-01-02`}}"
# Tell Packer to use SSH over SSM
communicator = "ssh"
ssh_interface = "session_manager"
ssh_username = "Administrator"
ssh_timeout = "10m"
}
Operating system and Environment details
Windows Server 2019 AMI Using MacBookPro to run Packer

I am getting the same results with a slightly different configuration targeting an Amazon Linux 2 AMI instead of a Windows AMI, and with a different ssh_username, as the issue describes. Packer version 1.8.3.
As a side note, my configuration below uses a non-default VPC. It works when I use the ssh_username = "ec2-user" but fails when I set it as shown below to ssm-user.
source "amazon-ebs" "my-ami" {
# ... snipped some details like name, IAM role ...
ami_virtualization_type = "hvm"
secret_key = "${var.aws_secret_key}"
source_ami = "${data.amazon-ami.amzn2-latest.id}"
communicator = "ssh"
ssh_interface = "session_manager"
ssh_username = "ssm-user"
subnet_id = var.my_subnet
vpc_filter {
filters = {
isDefault = "false"
"tag:Name" = var.vpc_name
}
}
}
I'm getting the same problem. Windows_Server-2019-English-Full-Base latest AMI, Packer running on Ubuntu (GitAgent Action agent).
