我一直在尝试 在Ubuntu 16.04上 使用 Docker(1.10), 但安装失败,因为 Docker Service无法启动 。我已经尝试通过 docker.io和docker -engine apt软件包安装 docker ,curl -sSL https://get.docker.com/ | sh但是它不起作用。
curl -sSL https://get.docker.com/ | sh
我的 主机信息 是:

如果有人可以帮助我,我将非常感激
更新资料
似乎在较新版本的docker和Ubuntu中,只是简单地屏蔽了docker的单元文件(指向/ dev / null)。 您可以通过在终端中运行以下命令来验证它:
sudo file /lib/systemd/system/docker.service sudo file /lib/systemd/system/docker.socket
您应该看到单位文件符号链接到/ dev / null。 在这种情况下,您要做的就是遵循S34N的建议,然后运行:
sudo systemctl unmask docker.service sudo systemctl unmask docker.socket sudo systemctl start docker.service sudo systemctl status docker
我还将保留原始帖子,该帖子回答了错误日志,指出应替换存储驱动程序:

我遇到了同样的问题,我尝试按照Salva Cort的建议修复它,但是打印时/etc/default/docker说:
/etc/default/docker
#此文件不适用于系统
因此,这是一个适用于systemd(Ubuntu 15.04及更高版本)的永久修复程序:
创建一个/etc/systemd/system/docker.service.d/overlay.conf具有以下内容的新文件:
/etc/systemd/system/docker.service.d/overlay.conf
[Service]
ExecStart= ExecStart=/usr/bin/docker daemon -H fd:// -s overlay
通过执行以下命令清除更改:
sudo systemctl daemon-reload
验证配置是否已加载:
systemctl show --property=ExecStart docker
重新启动docker:
sudo systemctl restart docker
