I have just built your config.scm successfully.  (I'm not suru but) it
looks like you either have a broken store or some stale files in the
partition you want to initialize the system to.

Could you try the following from your Lubuntu (without 'sudo'):

  guix pull
  guix system build --no-grub /path/to/your/config.scm

If the system has been built successfully (it definitely should), make
sure your partition is absolutely empty (!) and init the system there:

  sudo -E guix system init --no-grub /path/to/your/config.scm <mount-point>

--
