Docker: cgroup devices not installed (Ubuntu 16.04)

Question

I am trying to install docker on Ubuntu 16.04 on a remote web server. However, I get an error message that really upsets me. I have installed docker many times, as well as on this OS, but this never happened.

I am stuck in sudo apt-get install -y docker-engine when sudo apt-get install -y docker-engine cannot be installed:

I added root to the group, I also found advice to add GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1" to the file / etc / default / grub, but this file does not exist!

I also tried sudo apt-get install cgroupfs-mount , but to no avail: - (

Thank you for your help!

So guys. Unfortunately, there is no solution. The reason is the architecture of the remote web server hosted by the virtual machine. My provider told me that all virtual machines use the same cores in the same environment, and therefore dokker cannot access it.

The only option is to switch to another server.
