docker-engine运行级别:/var/run/utmp:没有这样的文件或目录

Question

我正试图在Ubuntu 14.04的一个虚拟实例上安装Docker，该实例来自一个服务提供商，该服务提供商可能已经修改了一些默认的底层init系统或文件系统。

当尝试执行apt-get安装最新的docker-engine时，我得到以下错误。有什么办法可以让我试试吗？

My installation steps:

sudo apt-get install --yes apt-transport-https ca-certificates
sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

echo "deb https://apt.dockerproject.org/repo ubuntu-trusty main" | sudo tee /etc/apt/sources.list.d/docker.list

sudo apt-get update

apt-cache policy docker-engine

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

The one giving errors is this one:

cgroup (控制组)是在linux系统上管理容器的固有部分，所以看起来您没有权限。要么你没有root，要么他们已经被锁定了。
