Eu corro o Ubuntu 14.04LTS, 64 bits. Tentei executar o Software Updater, mas tive a mensagem "Falha ao baixar informações de repositório. Verifique sua conexão com a Internet" ( captura de tela ).
Eu corri apt-get update , e isso me deu isso:

Eu tentei mudar o servidor espelho para vários outros, incluindo "Servidor principal", mas o resultado é o mesmo. O erro parece vir de /etc/apt/sources.list ou de /etc/apt/sources.list.d/* .
Aqui está o /etc/apt/sources.list :

Também desmarcou todas as caixas "Outros softwares" do programa "Software e atualizações", apenas para ver se o problema é proveniente de um pacote não oficial, mas não parece.
Alguma ideia para resolver isso?
