在 Ubuntu 18.04 上启用 IPv6

我按照这个教程操作（https://www.digitalocean.com/docs/networking/ipv6/how-to/enable/) 在 DigitalOcean 上启用我现有的 Ubuntu 18.04.3 LTS Droplet 的 IPv6。我的服务器在 /etc/netplan 中没有任何内容，因此我按照 Ubuntu 16.04 的说明并更改了 /etc/network/interfaces。我添加了建议的内容（更改了我在启用 IPv6 时在 DigitalOcean 仪表板上获得的 IPv6 地址）。服务重启后，我得到了：

  1. 知道可能是什么问题吗？
  2. 为什么我的服务器仍然使用旧的网络方式（而不是 netplan）？我不记得了，是不是以前升级过？

问候。
