Question

我正在尝试在ubuntu版本16.04.01上安装docker，安装后出现错误，包有docker-engine错误。当我尝试通过命令docker daemon -D启动docker服务时我得到这个日志：

我正在使用由另一家公司托管的服务器，这是ubuntu的预装版本，我已经尝试多次重新安装它并重新执行它但是没有用。

这对我有用。

更新软件包信息，确保APT与https方法一起使用，并且已安装CA证书。

 $ sudo apt-get update
 $ sudo apt-get install apt-transport-https ca-certificates

添加新的GPG密钥。

$ sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

在docker.list中为您的Ubuntu操作系统添加一个条目：

$ vi /etc/apt/sources.list.d/docker.list（不存在）

含量：

deb https://apt.dockerproject.org/repo ubuntu-xenial main

并保存（：wq）

更新APT包索引。

$ sudo apt-get update

清除旧的仓库（如果存在）（之前的安装）。

$ sudo apt-get purge lxc-docker

验证APT是否从正确的存储库中提取。

$ apt-cache policy docker-engine

更新您的包管理器。

$ sudo apt-get update

安装推荐的软件包。

$ sudo apt-get install linux-image-extra-$(uname -r)

安装Docker。

$ sudo apt-get install docker-engine

启动docker守护程序。

$ sudo service docker start

验证码头已正确安装。

$ sudo docker run hello-world

附加：您可以创建一个泊坞组。我的回答来源：the official documentation of docker。
