Amostra de /etc/apt/sources.list para o Linux Mint 17

Question

Parece que meu arquivo /etc/apt/sources.list tem apenas

deb cdrom:[Linux Mint 17 Qiana - Release amd64 20140624]/ trusty contrib main non-free

Ele pode ter sido corrompido quando eu estava tentando fazer o download de pdfedit . Quando tento baixar algum software agora diz:

This is a major failure of your software management system. Please check for broken packages with synaptic, check the file permissions and correctness of the file '/etc/apt/sources.list' and reload the software information with: 'sudo apt-get update' and 'sudo apt-get install -f'.

    

Answer 1

Do meu próprio sistema, um Linux Mint 17.1 Rebecca, o arquivo /etc/apt/sources.list.d/official-package-repositories.list contém isto:

deb http://packages.linuxmint.com rebecca main upstream import 
deb http://extra.linuxmint.com rebecca main
deb http://archive.ubuntu.com/ubuntu trusty main restricted universe multiverse 
deb http://archive.ubuntu.com/ubuntu trusty-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse 
deb http://archive.canonical.com/ubuntu/ trusty partner

Meu /etc/apt/sources.list está vazio.
