Error cuando intento actualizar ubuntu

Al parecer estas tratando de utilizar los repositorios de Debian en Ubuntu. Podrias por favor adjuntar el contenido del archivo /etc/apt/sources.list?

Este es mi fichero sources.list

Existe el directorio /etc/apt/sources.list.d? en caso de ser positiva la respuesta, puedes colocar el contenido de los archivos que se encuentren alli?

Podrias ademas pegar la salida del siguiente comando (se debe ejecutar en consola):

sudo apt-cache show libglobus-gsi-credential-dev

Gracias

Hola compañero yo también tenía el mismo problema, así que me fui a la terminal y teclée:
sudo nautilus
me fui a etc/apt/sourcelist y efectivamente me dí cuenta que mi lucid lynx utilizaba los repositorios de jaunty jackalope y de fesity, lo que hice fue seleccionarlos y le dí quitar, et voila!! eso era todo. espero que te sirva
