Stack is in UPDATE_COMPLETE_CLEANUP_IN_PROGRESS state and can not be updated

Question

I'm trying to deploy a Lambda function inside Cloud9, but it is failing.

When I right-click on the function and click Deploy, I get Application deployment failed, and then a popup:

AWS CloudFormation Deployment Errors
Stack:arn:aws:cloudformation:* is in UPDATE_COMPLETE_CLEANUP_IN_PROGRESS state and cannot be updated.

Answer 1

I ran into this issue deploying using the serverless framework.

The solution ended up just being waiting, but it took almost a full hour for the state to clear itself. There were no new events showing up. I just had to wait a long, long time.

Answer 2

If your deployment is building another Stack in CloudFormation, you may want to check for existing ones with the same name that may be conflicting with the Stack created by your deployment.

Go to CloudFormation, find the conflicting Stack, delete all resources (in that stack), and finally delete the stack.

Deploy again and it should work this time.
