Apt-Get更新：无法获取；无法连接到任何来源

22

我意识到有数十个“易于获取更新：无法获取”的问题（我通读了所有内容），但是我目前的情况是12.04独有的，它影响所有来源。不只是启动板。另外，我在欧洲和美国尝试了几种不同的服务器以及“主服务器”（无论在哪里），它们都产生相同的结果：我无法连接到任何软件源。

另外，我可以肯定地认为问题出在我今天早上从11.10-> 12.04进行升级，因为更新之前就可以进行。

来自更新管理器的更新工作正常，我可以从软件中心下载某些内容（杂音）而不会发生任何故障，这让我认为我可以连接到Ubuntu服务器的某些子集（但是，其他一些Ubuntu服务器（例如其他功能）并且某些规范服务器被列为“无法连接”）。

这是来自的输出sudo apt-get update：

是的，名称服务器更新确实起作用，如果它起作用了，那么您可能已将IP设置更新为静态，并且服务器不再能够解析URL。

请尝试以上操作，如果可以，请重新启动。如果重新启动后失败，请执行以下操作：

编辑的模板文件resolv.conf。Ubuntu服务器会在每次启动时重建它。

sudo vi /etc/resolvconf/resolv.conf.d/tail

#add just these two lines >>
nameserver 8.8.8.8
nameserver 8.8.4.4

然后保存文件并重新启动服务：

sudo /etc/init.d/resolvconf restart

8.8.8.8而8.8.4.4只是谷歌的名称服务器。如果需要，您应该可以添加自己的ISP。如果您不喜欢vi，请使用nano或vim。

我看完这篇文章就明白了。因此，请给他们小费。

将名称服务器选项添加到/etc/resolvconf/resolv.conf.d/tail并不是解决任何问题的方法。首先，提供给resolvconf的任何其他地址将优先。其次，名称服务器配置通常必须是动态的（取决于网络环境和活动的接口），而tail文件是静态的。除此之外，没有迹象表明所报告的问题是名称解析之一。

我刚刚在这里找到答案。显然apt无法处理很多软件资源，因此我能够通过取消选择除需要访问的软件之外的所有软件来解决我的问题。经常这样做确实很痛苦，但是总比没有好。从站点：

在“其他软件”选项卡上，禁用所有PPA存储库，仅保留官方的Ubuntu存储库。启用过多的PPA存储库（非官方的存储库）会导致程序包管理器变得不稳定。

您可以在此处引用相关代码段以供将来参考吗？

将行添加nameserver 8.8.8.8到您的/etc/resolv.conf。

设置备用DNS服务器（由Google运行的公共DNS服务器），以防出现DNS问题。它与其他答案相似（尽管不完全相同）（稍后发布，并针对基本相同的重新配置提供了不同的方法）。

这是由某些代理程序包（例如anon_proxy）引起的，它使用环境变量通过本地代理传递所有HTTP连接。因此，要更改此编辑/ etc / environment并在最后两行中注释掉HTTP_PROXY和http_proxy。

同样的问题也把我带到这里。我正在使用Ubuntu Server 12.04。上述解决方案都没有解决我的问题，因此我尝试了其他解决方案。

我只是打开了/ etc / apt上的sources.list，发现其中一些源是“受限制的”。

只需编辑sources.list并删除“ restricted”参数，它现在就可以正常工作了：）

希望对别人也有用！

本restricted部分是Ubuntu存储库中的官方部分。除非您确实想要运行仅FOSS的软件，否则不要将其删除。参见askubuntu.com/a/251606/88802。我不确定为什么它对您有用-我认为这没有任何意义。
— gertvdijk
但是我的服务器现在怎么更新？删除该参数后。有任何想法吗？
— RustanTech

我认为您没有相同的问题。“无法连接到...”（如在OP中）与存储库部分的配置完全无关。
