我一直在尝试在Ubuntu 14.04的Linode实例上安装docker。我到最后一步得到消息： E：无法找到包docker-ce
我已经按照许多不同网站中的这一系列步骤进行操作，但没有运气：
sudo apt-get remove docker docker-engine docker.io
sudo apt-get update
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
sudo apt-get update
sudo apt-get install docker-ce
这是我在运行apt-get update时看到的内容：

关于可能有什么不妥之处的任何建议？我在一个新的Ubuntu 16.04实例上运行了相同的命令集，并且Docker安装得很好。这个14.04实例有很多事情发生，所以我不倾向于从一个新的开始。

**您好， 您可以尝试在此页面上下载.deb文件：
https://apt.dockerproject.org/repo/pool/testing/d/docker-engine/
然后使用以下命令进行安装：
sudo dpkg -i /path/to/package.deb
要确保已安装，只需键入：
sudo docker运行hello-world
就是这样。 希望它能起作用！
