我尝试使用do-release-upgrade命令将 Ubuntu 16.04 升级到 18.04，但升级后 DNS 解析失败。我实际的意图是升级到 20.04，但由于我使用的是 16.04，所以我必须先升级到 18.04。
Ping 谷歌 IP 没问题，但 DNS 本身就不行。我添加了nameserver 8.8.8.8并/etc/resolv.conf根据/etc/resolvconf/resolv.conf.d/head提供的解决方案从 16.04 升级到 18.04 后没有互联网但是当我尝试重新启动网络（sudo /etc/init.d/networking restart）时，它失败并出现以下错误：
Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xe" for details.
failed!

如何修复？或者有没有办法再次进行干净升级来解决所有这些问题？
