No se ha podido inicializar la información de los paquetes

[Carlos]

Ha ocurrido un problema imposible de corregir cuando se inicializaba la información de los paquetes.

Por favor, informe de esto como un fallo en el paquete «update-manager» e incluya el siguiente mensaje de error:

'E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_quantal-security_main_i18n_Translation-en, E:No se pudieron analizar o abrir las listas de paquetes o el archivo de estado.'

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your bug report it seems that you are experiencing bug 346386. This issue happens when you have tried to update your package information when you are a network that didn't return the right files. This issue can be cleaned up by using the following commands in a terminal:

1.) sudo rm /var/lib/apt/lists/*
2.) sudo apt-get update

Thanks and good luck!
