Bug Description
On a Ubuntu 16.04 server amd64 host, docker does not work inside of a (lxc or lxd) Ubuntu 14.04 guest.
I tested on both a clean Ubuntu 16.04 install and also one that was upgraded from Ubuntu 15.10.
My definition of work is having the expected result when running
-------
sudo docker run hello-world
-------
If the guest containers is also Ubuntu 16.04, it works out of the box.
The images were made either using
lxc-create -t download -n test01 -- -d ubuntu -r trusty -a amd64
or on lxd following the syntax from https:/
Just for further reference, If the host is 15.10, one can have docker inside of LXC containers if one does the following:
a) on the host:
add this to /etc/lxc/
lxc.aa_profile = unconfined
lxc.cgroup.
lxc.cap.drop =
sudo mv /usr/share/
iptables -L # really. this loads modules that the docker install needs to be happy
ip6tables -L # really. this loads modules that the docker install needs to be happy
create the guest with something like
lxc-create -t download -n test01 -- -d ubuntu -r trusty -a amd64
b) on the guest
sudo apt-get install curl apparmor cgroup-lite
curl -fsSL https:/
sudo docker run hello-world
I personally consider this bug very important because 15.10 will be unsupported in July, so not upgrading will become an insecure choice to make.
If there is any way I can help you, please let me know.
Thanks
Marcos

This is not a lxd bug. You need the docker source as is packaged in
16.04. To run that in a 14.04 container, you might be able to build
the 16.04 package in a ppa for 14.04, but I've not tried it. Marking
this as affecting docker.io
