You need to enable the xenial-backports repository in the install
process with more priority. apt policy is saying that backports have
*less* priority that the updates and security repository.

if i do this

/*apt policy lxc -t xenial-backports*/

i get this:
**/**/

lxc:
  Installed: (none)
  Candidate: 3.0.2-0ubuntu4~16.04.1
  Version table:
     3.0.2-0ubuntu4~16.04.1 990
        990 http://archive.ubuntu.com/ubuntu xenial-backports/main amd64
Packages
     2.0.8-0ubuntu1~16.04.2 500
        500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64
Packages
     2.0.7-0ubuntu1~16.04.2 500
        500 http://security.ubuntu.com/ubuntu xenial-security/main amd64
Packages
     2.0.0-0ubuntu2 500
        500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages

You will see that now 3.0.2 have more priority and you can do:

/*sudo apt install lxc=3.0.2-0ubuntu4~16.04.1 -t xenial-backports*/


and lxc 3 will be installed cleanly in your xenial machine.
