Acabei de adquirir espaço no servidor com um provedor de VPS. A primeira coisa que eu queria fazer é instalar a versão mais recente do Nginx. Eu segui as instruções oficiais do Nginx conforme descrito aqui . Tudo correu bem até que eu corri sudo apt-get update . Por alguma razão, parece que todos os repositórios em /etc/apt/sources.list atualizam corretamente, exceto aqueles para o Nginx que eu adicionei manualmente.
Eu tenho um servidor de teste na minha LAN que eu configurei exatamente da mesma forma que o servidor virtual virtual, então eu sei que a configuração funciona.
Sou relativamente novo em tudo isso, não tenho ideia do que pode estar causando isso, e não consegui encontrar ninguém on-line que tivesse o mesmo problema, mas tentei essas etapas de diagnóstico pelo que consegui encontrar:
Removeu todos os servidores de nomes em /etc/resolv.conf e adicionou apenas 8.8.8.8 do Google - não resolveu o problema e todos os repositórios tiveram erros quando executei sudo apt-get update
Sempre que tento ping , a saída é sempre connect: Network is unreachable
mas se eu executar host www.google.com , por exemplo, recebo esta saída:
www.google.com has address 74.125.28.147
www.google.com has address 74.125.28.99
www.google.com has address 74.125.28.103
www.google.com has address 74.125.28.104
www.google.com has address 74.125.28.105
www.google.com has address 74.125.28.106
www.google.com has IPv6 address 2607:f8b0:400e:c04::93
Esta é a saída de sudo apt-get update
