Como consertar duplicatas aparentemente autogeradas em sources.list em 14.04 LTS? [duplicado]

Question

Então eu passei pela pergunta Como corrigir a entrada de sources.list Duplicada? e a maior parte da resposta, mas esse problema não parece ser corrigido. O erro que estou recebendo é:

O que tentei é

• excluindo o arquivo source.list
• sudo mv /etc/apt/sources.list.d /etc/apt/sources.list.d.bak
• sudo rm /etc/apt/sources.list.distUpgrade
• removeu um repositório de origem duplicado e garante que não haja outro

O comando que estou usando é sudo apt-get clean && sudo apt-get update . Tentei mesmo sem a limpeza.

Como posso resolver este problema?

Histórico:

1. Meu Emacs Tramp está dando o erro cond: Couldn't find a proper 'ls' command . Então tentei as respostas aqui . Mas nenhum resultado.

2. Tentei compilar o Emacs 24.4 (não disponível no centro de software). Não foi possível devido a ( sudo apt-get build-dep emacs24 ):

   The following packages have unmet dependencies:
   libgtk-3-dev : Depends: libgtk-3-0 (= 3.10.8-0ubuntu1.2) but 3.12.2-0ubuntu4~trusty1 is to be installed
   E: Build-dependencies for emacs24 could not be satisfied.
   

3. Então eu encontrei este . O que disse para consertar pacotes quebrados usa o comando sudo apt-get clean && sudo apt-get update

Answer 1

Eu não posso comentar, então tenho que adicionar isso como resposta.

Você pode mostrar sua sources.list?

Eu não acho que o problema seja com sources.list.d / *. list porque o erro é com o repositório multiverso ubuntu. Aposto que você tem duas entradas do multiverso de backports confiáveis em seu /etc/apt/sources.list de alguma forma. Pode ser uma única linha duplicada, ou algo parecido com

deb http://archive.ubuntu.com/ubuntu trusty-backports main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu trusty-backports multiverse

Abra o seu sources.list em um editor de texto, localize as duplicatas e exclua as linhas extras.
