Auto Scaling group EC2 instance launch failure - amazon-web-services

Question

I'm trying to bring up a CloudFormation stack to run an ECS service on EC2. My stack creation fails upon creation of the Auto Scaling group and the error in the console Activity tab shows:
Status: Failed
Description:
Launching a new EC2 instance. Status Reason: The requested configuration is currently not supported. Please check the documentation for supported configurations. Launching EC2 instance failed.
Cause:
At 2020-10-26T23:47:46Z a user request update of AutoScalingGroup constraints to min: 1, max: 1, desired: 1 changing the desired capacity from 0 to 1. At 2020-10-26T23:47:48Z an instance was started in response to a difference between desired and actual capacity, increasing the capacity from 0 to 1.
I have tried to play around with my CFT but with no luck so far.

Answer 1

Based on your parameter defaults, you're trying to launch an Ubuntu Server 20.04 x86 AMI (ami-0dba2cb6798deb6d8) on an instance type (c6g.4xlarge) that requires an ARM based AMI.
Try switching the AMI to ami-0ea142bd244023692, which (at the time of this writing) is the ARM based AMI for Ubuntu Server 20.04
