解决方法1

resolvconf -u

 手动更新DNS 服务，但是重启后需要重新执行这个命令。

解决方法2

1、检查状态

systemd-resolve --status
# systemd-resolve --status
Failed to get global data: Unit dbus-org.freedesktop.resolve1.service not found.

2、重新连接服务

sudo ln -sf /lib/systemd/system/systemd-resolved.service /etc/systemd/system/dbus-org.freedesktop.resolve1.service

3、重启服务 

sudo systemctl restart systemd-resolved.service

4、确认状态
