title: sudo: effective uid is not 0, is sudo installed setuid root?
body: <p>I am trying to create deb package from LXC rootfs, and after creating it 
  I want to install that package any computer. Up to this point I achieved 
  packaging and installing deb package, however after installation of LXC
  package, I cannot be superuser in that lxc. I get this error when I use
  <strong>"sudo"</strong> command.</p>
