hola soy principiante en el uso de ubuntu y desde hace unos dias aparece un un mensaje de error al momento de intentar actualizar el sistema (12.04) que dice:
"la informacion de actualizacion esta obsoleta. esto puede deberse a problemas en la red o que algun repositorio ya no esta disponible"
Y al actualizar me dice aparece el siguiente error:
W:Failed to fetch http://ppa.launchpad.net/canonical-dx-team/une/ubuntu/dists/precise/main... 404 Not Found

AL ESTAR BUSCANDO INFORMACION DEL PROBLEMA ME PERCATO DE QUE SON LOS REPOSITORIOS.
HE ENCONTRADO EL COMANDO PARA AGREGAR LOS REPOSITORIOS PERO NO SE CUALES SON A PESAR DE HABERLOS BUSCADO

sudo add-apt-repository ppa:XXXXXX
sudo apt-get update

sospecho que el problema no se limita a repositorios duplicados

NO grites, lee las normas del foro, no se permite abusar de las mayúsculas (gritar). Que un moderador te puede cerra el hilo.
Aunque dices que eres nuevo te pusiste a agregar cuanto programa (ppa) encontraste en la red, Los ppa solo son recomendables para programas que no estén en los repositorios del sistema. y luego lo que veo:
1-agregaste quien sabe como repositorios para 32 y 64 bits.
2-unos son para versiones anteriores que ya no existen para tu versión.
Para ver si se puede arreglar te pregunto, que programas instalastes, ya que creo que tambien rompiste el sistema de dependencias.
Por lo pronto mira aquí y ve si puedes instalar ppa-purgue.

revise las reglas del foro antes de publicar, busque información y tutoriales que aplique, esperando alguno fuera la solucion pero en fin....desconosco que tanto instale en esa busqueda.
pero creo que "super-boot-manager" fue de lo ultimo q instale entes de q hubiera problemas.
En este orden de ideas, el enlace que señalas me parece que refiere que puedo desactivar los ppa: desde origenes del software al deshabilitar las casillas de "canonical-dx-team" y "sourceslist.eu" ya puedo actualizar (creo por que aparecen actualizaciones en el Gestor), pero al instalar el ppa-purgue aparece lo siguiente:
$ sudo apt-get install ppa-purge
[sudo] password
Leyendo lista de paquetes... Hecho
Creando árbol de dependencias
Leyendo la información de estado... Hecho
ppa-purge ya está en su versión más reciente.
0 actualizados, 0 se instalarán, 0 para eliminar y 2 no actualizados.

vamos por partes;
cuando tengas que poner un texto largo como el anterior utiliza paste:
http://paste.ubuntu.com/
Esa fácil, solo pones el nombre, pegas el texto, y presionas paste, y el sistema te da un link que pones aquí para ir a ver.
Ahora el error de repositorios duplicados, entra en sistema, orígenes del software, hay una pestaña de externos, y desmarca los que no coincidan con tu sistema o sea 32 o 64 bits.

En orígenes del software, pestaña Otros software, desmarca los que no son de tu arquitectura 32, o 64 bits.
ppa-purgue es para como su nombre lo dice, borrar o purgar repositorios externos.
Ya que des-habilites los ppa externos, trata de actualizar desde la terminal, con :
sudo apt-update y mira si te da un error.

entiendo que la arquitectura del sistema es de 64 bits es decir "amd64", por lo tanto debo desmarcar todo lo que señale la arquitectura de 32 bits "i386" el problema es que no aparece ninguna opcion que señale "i386"; aparecen casi todos los repositorios repetidos pero con un parentesis al final que dicen (Código fuente) pero ninguno señala "i386" y por los errores que me aparecen la introducir "sudo apt-get update" en la consola se supone que deberia de tener esas opciones disponibles pero es el caso que solo aparecen "amd64"

y bueno si desmarco todas las casillas (*) en origenes del software ya no me aparece ningun error al actualizar, no se si eso valga como solucionado
