Olá

Se tivesse feito uma pesquisa no fórum antes de postar como leu nas regras que aceitou ao se cadastrar....

Teria visto que erro 404 é de conteúdo não encontrado.

Seguindo a pesquisa, teria visto que o Ubuntu 14.10 utopic unicorn já perdeu o suporte, e com isto seus repositórios foram retirados do "incoming"

Pesquisando mais a fundo, teria descoberto que os repositórios sem suporte são movidos para old-releases.ubuntu.com.

Neste ponto você teria uma dúvida, manter o 14.10 alterando os repositórios para os old-releases ou atualizaria o sistema para o 15.04?

E a resposta deveria ser: você é o dono do sistema, só você para decidir.

Se quer manter o 14.04, tem na pesquisa no fórum como alterar para os old-releases. Se quer atualizar, tem na pesquisa do fórum a solução.

Abraços e bons estudos

Uma opção é instalar o 14.04 LTS com suporte até 2019.
