Overview of the Issue

When building multiple amazon AMIs, one of them always fails with ResourceNotReady: exceeded wait attempts. Adding aws_polling block doesn't help, I tried up to a combined wait of up to 3 hours. Running the same packer config with parallel builds disabled (-parallel-builds=1) succeeds without even aws_polling block.

Reproduction Steps

Steps to reproduce this issue

1. Save the file below as aws-ubuntu.pkr.hcl in an arbitrary new folder.
2. Run packer build . in the same folder

Notes:

• I tried adding a plugin block to update the amazon plugin but the result was the same.
• I have also tried using the docker image hashicorp/packer instead of the locally installed packer but the result was the same.
