我正在尝试从可能修改了某些默认底层init系统或文件系统的服务提供商在Ubuntu 14.04的虚拟实例上安装Docker。
当尝试对最新的docker-engine进行apt-get安装时，我会在下面看到这些错误。有什么想法我可以试试吗？
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）是如何在linux系统上管理容器的固有部分，所以看起来你没有那里的权限。要么你没有root，要么他们被锁定了。
