apt-get geralmente falha, com pacotes de software e com atualização

Question

Estou executando uma VM do servidor Ubuntu 14.04.4 usando a caixa virtual. Eu configurei a rede para estar na configuração "adaptador em ponte". Eu atribuí manualmente o IP do mesmo endereço da rede em que a máquina do Windows está ligada. Gateway é o roteador sem fio. Eu sou capaz de ping IPs públicos e URIs estão sendo traduzidos também.

Quando tento instalar um pacote de software como 'chrony', com sudo apt-get install chrony , recebo a seguinte saída imediatamente.

root@controller:~# apt-get install chrony
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package chrony

Quando tento atualizar o apt com sudo apt-get update , obtenho a saída,

    root@controller:~# apt-get update

Eu tentei desativar o roteamento IPv6 para isso. Eu não enfrento tal problema com as tentativas anteriores, me sinto perplexo depois de três dias. Qualquer insight seria apreciado. Parece que eu perdi algo claramente óbvio, mas sendo indiferente a isso.

Muito obrigado.

    

Answer 1

Tente executar o ping ' google.com ' ... e se ele não conseguir fazer o ping, faça o seguinte:

Edite /etc/resolv.conf e adicione

AVISO: você pode usar qualquer editor de texto, por exemplo, ' vi /etc/resolv.conf '

nameserver 8.8.8.8
nameserver 8.8.4.4

No final de /etc/resolv.conf - ou no topo, se estiver em arquivo vazio.

Deve funcionar agora, por favor me diga o que aconteceu nos comentários:)

EDITAR: notei em / etc / network / interfaces - que você já tem o campo "dns-nameservers" iniciado nos Google Nameservers, mas tente fazer isso também no meu método:)

    

Answer 2

EDITAR: Bem! essa solução vai 100% consertar (espero) ... Porque eu tentei usar a sua cópia ' sources.list ' e eu peguei o mesmo problema ... Depois disso eu tentei reverter o padrão 'sources.list' usando o método abaixo e 100% worke d (Testado!) :)

Bem, como suas configurações de rede estão bem e você é capaz de pingar tudo bem. Vamos restaurar o arquivo ' sources.list ' padrão da sua instalação do Ubuntu.

Então comece excluindo o corrompido ' sources.list ' e vamos substituí-lo nas próximas etapas:

sudo rm /etc/apt/sources.list

Agora abra ' software-properties-gtk ', que criará automaticamente um novo arquivo ' sources.list ' vazio

sudo software-properties-gtk

Em ' software-properties-gtk ', marque (check) ' Community-maintained free and open-source software (universe) '

Em seguida, defina ' Download from: ' como ' Server for USA ' ou qualquer servidor que esteja próximo da sua localização.

E, claro, clique no botão ' Revert '.
