在 Kubuntu 17.04 Zesty 上,我不断收到错误 21 (net::ERR_NETWORK_CHANGED)。刷新后,页面加载正常。由于此错误,我的下载也中断了。在 Firefox 上一切正常。
此错误可能是什么原因造成的?我不认为这是由 WiFi 驱动程序引起的,因为在其他 Web 浏览器上我没有收到任何错误。

答案1
您在使用 Docker 吗?您有 Docker 网络吗?尝试删除它们(除了bridge
、host
和none
)。这为我解决了问题。
我在戴尔 Inspiron 13(5000 系列,英特尔公司 Wireless 3165(修订版 79))上使用 Kubuntu 16.10。此问题曾经在 IPv4 和 IPv6 网络中以及有线和无线网络中发生过。
您可以使用以下命令删除所有未使用的 Docker 网络:
docker network prune
答案2
您可以尝试使用以下命令禁用 IPv6。
sysctl -w net.ipv6.conf.all.disable_ipv6 = 1
sysctl -w net.ipv6.conf.default.disable_ipv6 = 1
如果有效,请将以下几行添加到/etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
