Google Chrome：错误21（net :: ERR_NETWORK_CHANGED）

在Kubuntu 17.04 Zesty上，我不断收到错误21（net :: ERR_NETWORK_CHANGED）。刷新后，页面加载良好。由于此错误，我的下载也被中断。在Firefox上一切正常。

该错误的原因是什么？我不认为这是由WiFi驱动程序引起的，因为在其他网络浏览器上，我没有出现任何错误。

您正在使用Docker吗？您有Docker网络吗？尝试删除它们（除bridge，host和none）。这为我解决了。

我在Dell Inspiron 13（5000系列，英特尔公司无线3165（修订版79））上使用Kubuntu 16.10。IPv4和IPv6网络以及有线和无线网络都曾经发生过此问题。

您可以使用以下命令删除所有未使用的Docker网络：

docker network prune
