我已经在 Ubuntu 16.04 中安装了 docker-ce，使用安装指南官方网站上给出了。安装 Docker 后，主机无法再连接到互联网。为了获得正确的互联网连接，我必须删除docker-ce并重新启动。
这个问题可能看起来类似于这，但是那篇文章中介绍的方法却不起作用。
我尝试了几件事：
- 我可以 ping 8.8.8.8，但不能 ping www.google.com。
dns=dnsmasq我尝试通过注释掉中的行来关闭网络管理器\etc\NetworkManager\NetworkManager.conf。但是没有用。- 我尝试将
8.8.8.8其设为 中的第一个名称服务器\etc\resolv.conf。这可行，但重启后会丢失，如文件中所述。 - 为了使上述更改永久生效，我使用了几种方法，例如添加
nameserver 8.8.8.8到head文件下\etc\resolvconf\resolv.conf.d和添加server=8.8.8.8到\etc\dnsmasq.conf。这些方法，从这里，互联网连接时断时续，速度非常慢。此连接不断中断。
默认名称服务器为etc\resolv.conf127.0.0.1。安装\删除 Docker 时此名称服务器不会更改。
