Déjame agradecerte de antemano por leer e intentar ayudarme. ¡Gracias! Perdón por la terrible edición, también tuve que cambiar algunos de los enlaces porque no tengo buena reputación :)
Mi problema es el siguiente: al abrir el centro de software de actualización aparece una ventana de error que dice: "Los elementos no se pueden instalar ni eliminar hasta que se repare el catálogo de paquetes..." Hago clic en reparar pero falla.
La ejecución de Sudo apt-get update falla, este es el informe de error:
"W: Failed to fetch archive.ubuntu.com/ubuntu/dists/precise/Release Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)
W: Failed to fetch bzip2:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise-updates_main_binary-i386_Packages Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old ones used instead."

2.
