Title:
  Not able to upgrade from 14.04 to 16.04

Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  When I try to upgrade from 14.04 to 16.04, using command "sudo update-
  manager -d" I get this error

  --------------------------------------
  No se ha podido calcular la actualización

  Ha ocurrido un problema mientras se calculaba la actualización.

   Eso se ha podido causar por:
   * Actualizar a una versión de Ubuntu aún no publicada
   * Estar ejecutando la versión actual, aún no publicada, de Ubuntu
   * Paquetes no oficiales de software no proporcionados por Ubuntu

  Si nada de esto aplica, informe de este error usando la orden «ubuntu-bug ubuntu-release-upgrader-core» en una terminal.
