class Aws::ECS::Types::UpdateInProgressException

There is already a current Amazon ECS container agent update in progress on the specified container instance. If the container agent becomes disconnected while it is in a transitional stage, such as `PENDING` or `STAGING`, the update process can get stuck in that state. However, when the agent reconnects, it resumes where it stopped previously.
