Tu file de Ubuntu configurado no puede ser resuelto. Si tiene un file interno, asegúrese de que está funcionando y de que está usando el nombre de host correcto. Si no es así, edite /etc/apt/sources.list para apuntar a " http://archive.ubuntu.com/ubuntu " en lugar de " http: //ubuntu-12.04.pxe/ ". Ejecute apt-get update después.

Edit : Parece que DNS no funciona en su sistema en absoluto. Compruebe que tiene los serveres DNS correctos enumerados en /etc/resolv.conf y que puede hacer ping a ellos.
