I am already using AWS Opsworks 11 which shows Ubuntu 14.04 LTS in the OS dropdown list. I already have running instances in layers (Ubuntu 14.04), but when I try to add new instances then it throws me an error:
ServiceError: Os: is not supported in this region, Root Device Type: must be included in .
Did AWS Opsworks 11 dropped support for Ubuntu 14.04? If yes then why the OS is still in the list?
PS. I can add Amazon linux AMI instances in that stack.
