"Não foi possível conectar-se a 80.112.143.217:80", por quê?

Depois de instalar uma nova cópia do Ubuntu 14.04 baixada do ubuntu.com, estou tentando instalar alguns pacotes, seja nodejs ou apache2, ele sempre diz nome não encontrado. Pesquisei um pouco e encontrei algumas respostas aqui

Não foi possível instalar arquivos com o apt-get: “não foi possível localizar o pacote”

mas nenhuma solução funcionou para mim. Já tenho todas as fontes habilitadas -

Além disso, tentei sudo apt-get updatemuitas vezes, mas ele retorna

Alguma saída como esta dizendo que não foi possível baixar ou encontrar pacotes ou algo parecido -

O que eu deveria fazer agora

Responder1

Como o erro com o mesmo endereço IP aparece em cada tentativa de conexão com um servidor que fornece pacote Ubuntu, acho que você configurou um proxy web usando o IP 80.112.143.217 e a porta 80.

Uma rápida pesquisa no Google me mostra que de fato este IP está associado a um proxy web público.

Atualmente ele não está respondendo a nenhuma pergunta, então posso não estar executando agora. Tente remover a configuração de proxy: System settings-> Network-> Network proxy. Remova ou altere o endereço do proxy para um que esteja funcionando e clique em Apply system wide.

Parece que você está usando um proxy para se conectar aos repositórios. Talvez o arquivo de configuração em /etc/apt/apt.conf esteja errado. Por favor verifique o conteúdo. Deve estar no formato:

Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";
Acquire::ftp::proxy "ftp://<username>:<password>@<proxy>:<port>/";
Acquire::https::proxy "https://<username>:<password>@<proxy>:<port>/";

nome de usuário não pode ser um e-mail!!! - nome de usuário e senha podem estar vazios - remover < >

Se você conseguir se conectar diretamente à Internet, simplesmente exclua o arquivo /etc/apt/apt.conf. (Também é recomendável fazer backup primeiro :)) Todas essas informações se aplicam ao Ubuntu 12.04 a 14.04 (até onde eu sei)
