Actualizacion de ubuntu alfa 4 hasta hoy dia 24 de agosto en karmic koala

Aunque ultima mente solo ponga actualizaciones , sera que es verano y no tengo ganas de estar tanto tiempo delante del pc , Por otra vanda la ultima actualizacion mu bolvio inservibre el sistema ya que me recomedanan quitar una serie de paquetes que conserver y no lo hice así que no podia iniciar el sistema ya que cuando debia cargar el entono grafico se quedaba una pantalla en negro asi que opte por esta opcion , de actualizar desde el alfa.
