¿Por qué después de una nueva actualización de instalación de Ubuntu 12.04 no se están instalando?

He instalado Ubuntu 12.04 en una computadora. Todo está bien sin actualización. Justo después de la instalación, mostraba aproximadamente 200 MB de actualizaciones para descargar. Desde entonces estoy intentando instalar todas las actualizaciones. Ahora está parcialmente completado, parte del software (firefox, VLC) está actualizado. Todavía muestra actualizaciones de 39.3 MB para descargar y falla una y otra vez. Cada vez que traté de instalar estas actualizaciones de 39.3 MB, muestra que no se puede conectar a Internet, pero no hay ningún problema con mi conexión (el indicador de red muestra que está conectado y puedo buscar y descargar cualquier cosa). Me está dando el siguiente mensaje:

Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch

Pensé que esto es un problema con la lista de fuentes. Entonces he dado el siguiente comando

sudo rm -vf /var/lib/apt/lists/partial/*

Anteriormente, me he enfrentado a un tipo similar de problema con una computadora diferente. En ese momento, esta solución funcionó para mí, pero ahora todavía estoy enfrentando este problema. Alguien, por favor, ayúdame a resolver este problema.

Aquí está la salida de sudo apt-get update

Si está trabajando en una organización, compruebe si hay un bloqueo FTP del firewall. Si el firewall bloquea el puerto FTP, entonces no le permitirá actualizar.

Respuestas:

Mi problema está resuelto ahora. Estoy publicando aquí la solución paso a paso. De la salida de sudo apt-get update, me enfrentaba al siguiente problema:

W: Failed to fetch gzip:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise-updates_multiverse_binary-i386_Packages  Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead.

Para resolver este problema, ingresé los siguientes comandos uno por uno.

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get clean
sudo apt-get autoremove
sudo apt-get update
sudo apt-get dist-upgrade

Entonces la salida fue

Acabo de que la lista de paquetes de archivos de Estados Unidos no coincida con la suma de hash en algunas nuevas instalaciones de 12.04.5. Solución más corta que funcionó para mí al menos:

# rm /var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise_*
# rm /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_precise*
# aptitude update
