我今天遇到了一个非常奇怪（且令人困惑）的问题，似乎无法解决。当我连接到本地网络（使用以太网或 wifi）时，网络似乎连接良好，网页加载。但大约 10 秒后，页面似乎无法再加载，我看到 chrome“没有互联网连接”错误。
但请注意，互联网仍然处于连接状态。
我发现其他博客也提到了类似的事情，下面是我可以从中收集到的一些有用信息。
ping 8.8.8.8 这实际上不起作用，它只是返回下面的内容，然后冻结
PING 8.8.8.8 (8.8.8.8) 56（84）字节数据。
我禁用了以太网/wifi 来查看另一个是否正常工作，但是没有。
在 wifi 运行的情况下，我运行了 ifconfig，它返回了预期的块，包括 ip 地址行
inet 地址：192.168.0.1 Bcast：192.168.0.255 掩码：255.255.255.0
我不知道下一步该尝试哪里，我正在考虑升级（就像在 Ubuntu 16.04 上一样）但不认为我可以在没有互联网连接的情况下升级（请注意，我确实有其他可以下载和使用 USB 的电脑）。
任何帮助都将不胜感激，因为到目前为止这个问题已经困扰了半天，我真的需要知道如何修复它（希望不需要完全格式化我的机器）。

我首先禁用了 wifi，运行了这个命令，然后重新启动了它。命令行中什么都没出现，网页可以工作，但在刷新约 15 秒后，它又停止工作了。

添加其他 DNS 域 我进入网络，然后选择我连接的 wifi 网络，并将以下行添加到“其他 DNS 服务器”。然后重新启动网络管理器再次测试，遗憾的是没有任何变化。

找到可能的（临时）解决方案。我使用 Docker 做了很多工作，我的机器上有很多 docker 网络。运行docker network prune以删除一些未使用的网络似乎有所帮助。
但请注意，我不知道为什么这能解决问题，也许有一个 Docker 站点的 IP 有问题，或者可能只是我本地的 Docker 站点数量太多。我会看看它是否/何时恢复，并在了解更多信息后更新此票证。
