Hola
Soy nuevo en esto así que no tengo mucha de nada ^^'
El problema es el siguiente, tengo un live USB con volumen persistente de Ubuntu 14.04.4 LTS (el disco duro del note esta muerto y mientras no tenga dinero para uno nuevo tendre que usar ubuntu desde el pendrive), esta version me ha funcionado relativamente bien hasta ahora (se pega un poco a veces, pero eso es por los cambios que se guardan en el volumen persistente por la velocidad de escritura de los usb), pero hoy, luego de reiniciar el sistema firefox no queria abrir, lo intente solo desde el lanzador y no abre, las demas aplicaciones que tengo ahi abren sin problema. intente usando clean y update, pero solo da error, lo mismo al desinstalar desde el centro de software o de actualizar firefox solo en vez de todo el sistema, sigue saliendo lo mismo:
Code:
ubuntu@ubuntu:~$ sudo apt-get cleanubuntu@ubuntu:~$ sudo apt-get update

Leyendo lista de paquetes... ¡Error!                                           
E: No pude sincronizar «mmap» - msync (5: Error de entrada/salida)
E: No se pudieron analizar o abrir las listas de paquetes o el archivo de estado.
Alguna idea de qué podría ser? o Cómo solucionarlo?

Desde ya gracias
