Sou novato na plataforma linux.Por favor, não marque esta questão como duplicada antes de a ler completamente!
Meu sistema está sendo executado no processador intel i5 e o SO que eu instalei recentemente é 64-bit Ubuntu 13.10 . Eu tive que instalar um conjunto de bibliotecas para a minha ferramenta de desenvolvedor android ( ADT ) para funcionar corretamente. Tudo começou com o linuxizing do meu sistema e ambiente de desenvolvimento!
Este é um dos links I processado para este fim.
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs
Eu também usei as dicas para acelerar o Ubuntu 13.10
Mas quando eu faço um sudo apt-get update , ele mostra as seguintes mensagens de aviso várias vezes várias vezes.

E: Some index files failed to download. They have been ignored, or old ones used instead.
Eu tentei resolver os problemas usando várias respostas neste fórum que está pedindo para editar o arquivo sources.list . Mas eu não tenho esse conteúdo ( binary-i686 or binary-i586 ) no meu arquivo sources.list.
Alguém pode me ajudar a resolver esse problema? Por favor, não esqueça de responder com os comandos, pois sei muito pouco sobre o linux terminal commands !!
Abra o arquivo sources.list ,
sudo gedit /etc/apt/sources.list
Remova as linhas que foram mencionadas acima. Salve o arquivo.
Para os PPAs que causam erro, você deve excluir esse arquivo PPA também do diretório /etc/apt/sources.list.d .
Depois disso atualize os repositórios executando,
sudo apt-get update
