apt/synaptic não consegue acessar a internet no Devuan Daedalus, outras ferramentas funcionam bem

  • 772

Estou em Devuan Daedalus usando internet via roteador WiFi.

Eu consigo acessar a internet em um navegador, baixar regularmente usando yt-dlpe instalar/atualizar usando pipxno terminal. Mas quando eu instalo/atualizo/atualizo pacotes usando aptou synaptic, isso não funciona.

Parece muito estranho, mas por que não consigo aptacessar synaptica internet?

Alguém pode ajudar? Alguma outra informação necessária?

  1. A primeira coisa que chama a atenção é o seu nslookup:

    
~$ nslookup deb.devuan.org
Server:     192.168.0.1
Address:    192.168.0.1#53

    que 192.168.0.1 não é um endereço IP global e normalmente só é encontrado dentro da sua rede doméstica/laboratório/empresarial.

    Há um fluxograma gráfico para ajudar a resolver o "IP ruim que está sendo fornecido a você".insira a descrição da imagem aqui

  2. Best Answer

    Houve um problema ao acessar deb.devuan.org. (Não sei os detalhes; alguém disse que tem a ver com servidores round robin)

    Quando troquei o espelho para http://dev1.ipacct.in/, tudo funcionou bem.

    Obrigado a todos pelas suas contribuições! Aprendi algumas coisas com seus comentários e respostas...

    Cumprimentos.
