Parameter encrypted is invalid: EBS block device in launch configuration

[inkblot]

I have an aws_launch_configuration with an ebs_block_device that looks like this:

ebs_block_device {
  device_name = "/dev/xvdf"
  snapshot_id = "${terraform_remote_state.images.output.master_snapshot_us-east-1}"
}

terraform is able to create this launch configuration (and the snapshot_id is a valid snapshot) but the autoscaling group is unable to launch instances and the activity history for the autoscaling group shows failed launches with this error message:

Launching a new EC2 instance. Status Reason: Parameter encrypted is invalid. You cannot specify the encrypted flag if specifying a snapshot id in a block device mapping. Launching EC2 instance failed.

I believe that this is essentially the same bug as #1862, but with respect to the aws_launch_configuration resource rather than aws_instance.

Hi @inkblot
do you mind if we close this as a duplicate of #5360 ? I believe it's exactly the same issue.

That looks right.

I have the same issue to create ASG from launch instance from template. I did not set any encryption while creating the launch template. any workaround this issue?
