Question

Esta é a mensagem de erro que recebo:

An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:
E:Encountered a section with no Package: header, 
E:Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_precise_main_i18n_Translation-en, E:The package lists or status file could not be parsed or opened.

Como faço para forçar o upgrade para o pacote mais recente?

Eu estou no 12.04 LTS e quero ir para o 14.04.1 LTS. A mensagem de erro só me permite fechar & amp; ao fazer isso, fecha todo o atualizador. da minha lembrança anterior, há um arquivo que preciso excluir. Eu não consigo lembrar qual.
