在VirtualBox客人中，Docker不在Ubuntu16.04上工作

Question

试图在Ubuntu16.04上向VirtualBox客户安装Docker --它不起作用。

我遵循了安装指南https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-using-the-repository：

$ sudo apt install apt-transport-https ca-certificates curl software-properties-common
...
done.

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
OK

$ sudo apt-key fingerprint 0EBFCD88
pub   4096R/0EBFCD88 2017-02-22
      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid                  Docker Release (CE deb) 
sub   4096R/F273FCD8 2017-02-22

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

$ sudo apt-get update
...
Reading package lists... Done

然后我试着安装了docker-ce并得到了错误：

$ sudo apt-get install docker-ce
Reading package lists... Done

下面是建议在前面的命令输出中看到的调试信息：

$ systemctl status docker.service

另外一个是：

$ journalctl -xe
...
-- The start-up result is done.
Sep 26 11:35:04 build-server systemd[1]: docker.service: Start request repeated too quickly.
Sep 26 11:35:04 build-server systemd[1]: Failed to start Docker Application Container Engine.
-- Subject: Unit docker.service has failed
...

此外，我还试图在调试模式下运行Docker，下面是输出：

$ sudo dockerd -D
...

...

不能搜索任何有用的东西。有什么建议吗？提前谢谢。

更新到最近点发布或LTS启用堆栈

有一些问题是指与旧版本的内核不兼容。还有一个帖子，它通过更新到最近的点发布来解决类似的问题。

我会试试最近的LTS启用栈。

不同存储驱动程序

快速修复可能会从设备映射器更改为描述这里 (或其他fs，例如aufs)的overlayfs。编辑/etc/docker/daemon.json文件并更改存储驱动程序：

{
   "storage-driver": "overlay2"
}

还有一些用于存储驱动程序的选项。
