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

Question

I am trying to install Docker on a virtual instance of Ubuntu 14.04 from a service provider that may have modified some of the default underlying init system or filesystem.

When trying to do an apt-get install of the latest docker-engine, I get these errors below. Any ideas what I could try?

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:

The cgroup (control groups) are an intrinsic part of how containers are managed on linux system, so it's seems you don't have permission there. Either you don't have root, or they've been locked down somehow.
