[ubuntu-ar] Fallan actualizaciones en 11.10

[Angel S. Cadoppi]

Hola a todos, se que este tema fue tratado hace varios días. En ese 
momento ya venía yo buscando en internet una posible solución sin 
resultado, por lo que también probé lo ahí sugerido, también sin 
resultado. Seguí buscando todos estos días, encontrando un sin fin de 
respuestas de distinta índole, pero nada.
Probé cambiar a distintos servidores de varios países incluyendo el 
servidor principal pero nada cambia.
Cuando lo intento por el lado del Gestor de Actualizaciones me indica 
que compruebe la conexión a internet, que por supuesto funciona 
correctamente, y
al intentar por consola con sudo apt-get update && sudo apt-get upgrade 
obtengo exactamente el mismo resultado.
Por si a alguien se le ocurre que me puede estar pasando les paso lo que 
me arroja la consola:
