经排查，发现安装文件中引用的yum.dockerproject.org网站已经停止运行，所依赖的docker-engine所有服务无法完成安装；也没有找到替代源地址，请问如何解决，以下是此网站公告：
“Notice: Shutting down dockerproject.org APT and YUM repos 2020-03-31
Docker will be shutting down the deprecated APT and YUM repositories hosted at “dockerproject.org” and “dockerproject.com” on the 31st of March 2020.
We noticed that this project is referencing one of these repositories, and recommend updating to use the “download.docker.com” repository to prevent disruption.
