Start by tracing GetFile through abstractclient.py and pythonclient.py, especially _create_client, scp_all_client, and _create_scp_all_client, using the reported SCPClient traceback as the entry point. Reproduce the failure on the stated Python, Paramiko, and scp versions if possible; done means the cause of the missing transport is identified and the affected behavior is verified.
