EC2 T3.Micro - cloudformation problem

[2u841r]

Every time I tried create on t3.micro, its failed. (Hyderabad AP-South-2 and Jakarta AP-Southeast-3 have t3.micro in the free tier.) 

• Set the size to t3.micro (in config.cfg)
• arch - not changed, because chatgpt says t2.micro and t3.micro same arch.

ec2:
use_existing_eip: false
size: t3.micro
image:
name: "ubuntu-jammy-22.04"
arch: x86_64
owner: "099720109477"
instance_market_type: on-demand

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: botocore.exceptions.ClientError: An error occurred (ValidationError) when calling the UpdateStack operation: Stack:arn:aws:cloudformation:ap-southeast-3:211125505961:stack/algo/213d93f0-4e3d-11ef-ba9a-0e594d2e6682 is in ROLLBACK_FAILED state and can not be updated.

after this https://trailofbits.github.io/algo/troubleshooting.html#error-failed-to-create-symlinks-for-deploying-to-localhost
no solve.

sudo rm -rf /etc/wireguard/*
rm -rf configs/*
./algo

Same IAM user, same policy not create problem in t2.micro.
Now I am happify using with 3 regions t2.micro. but I want to solve this.

Have you had a chance to go and look it up in the AWS console?

[2u841r]

in aws console/Cloudformation- there's still t2.micro, although I chagned in config.cfg
InstanceTypeParameter:
Type: String
Default: t2.micro
and in parameter InstanceTypeParameter t2.micro

Thank you, I deleted that Stack (rollback failed) from console, and it works.
(I didn't realize at first that I had to delete it manually, since its not deleted automatically)

CloudFormation Rollback Issue: The error message indicates that the CloudFormation stack is in a ROLLBACK_FAILED state, preventing updates. so delete the Existing Stack:

Go to the AWS Management Console.
Navigate to CloudFormation.
Find the stack related to your Algo deployment.
Select the stack and choose Delete. This will clean up any resources that were partially created.

Then retry, run ./algo
