Take any fresh installation of Ubuntu 16.04. I used Vagrant to reproduce this bug, but it also reproduces on my VM with Ubuntu 16.04 in Azure. 2. Upgrade kernel to current latest release (linux- image-4.4.0-36-generic). # uname -r 4.4.0-36-generic 3. Install Docker 1.11.2 from Ubuntu repositories (also can be reproduced with Docker 1.12.1 from official Docker repositories for Debian/Ubuntu): # apt install docker.io 4. Use overlayfs as storage driver in Docker.
