docker - 无法在Ubuntu Xenial上安装Docker:invoke-rc.d:初始化docker，操作 “start”失败

Question

我一直在尝试在Ubuntu 16.04上安装Docker，但是这引发了我无法自行解决的错误。

使用位于get.docker.com上的安装脚本:

root@m2dcs44rnq:~# wget -qO- https://get.docker.com/ | sh
# Executing docker install script, commit: 92d5116
+ sh -c apt-get update -qq >/dev/null
+ sh -c apt-get install -y -qq apt-transport-https ca-certificates curl >/dev/null
+ sh -c curl -fsSL "https://download.docker.com/linux/ubuntu/gpg" | apt-key add -qq - >/dev/null
+ sh -c echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial edge" > /etc/apt/sources.list.d/docker.list
+ [ ubuntu = debian ]
+ sh -c apt-get update -qq >/dev/null
+ sh -c apt-get install -y -qq --no-install-recommends docker-ce >/dev/null
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
invoke-rc.d: initscript docker, action "start" failed.
dpkg: error processing package docker-ce (--configure): subprocess installed post-installation script returned error exit status 1

 docker-ce
E: Sub-process /usr/bin/dpkg returned an error code (1)

systemctl status docker.service的输出:

和 uname -a:

Linux m2dcs44rnq 2.6.32-042stab127.2 #1 SMP Thu Jan 4 16:41:44 MSK 2018 x86_64 x86_64 x86_64 GNU/Linux

不幸的是，我已经尝试过手动下载软件包并使用dkpg进行安装，但是这也产生了同样的错误。

Answer 1

经过更多研究并查看了journalctl -u docker的日志后，我发现了以下行:

Apr 21 18:12:41 m2dcs44rnq dockerd[18728]: time="2018-04-21T18:12:41.088984468-04:00" level=fatal msg="Your Linux kernel version 2.6.32-042stab127.2 is not supported for running docker. Please upgrade your kernel to 3.10.0 or newer."

事实证明，Docker不支持我的内核。我的错。
