Ubuntu 18.04 sudo apt update 错误 + 互联网连接问题

我正在尝试通过名为 UTM 的虚拟机在我的 M1 上安装 Ubuntu 18.04。

问题是我的 ubuntu 中“未找到 wifi 适配器”，因此我尝试运行sudo apt update，但出现错误提示

所以我找到了一个类似问题（运行 apt-get update 时出错）的解决方案，它是

  1. 运行$ vi /etc/network/interfaces并添加dns-nameservers 8.8.8.8 8.8.4.4
  2. 运行$ vi /etc/resolv.conf并添加nameserver 8.8.8.8 nameserver 8.8.4.4 ，但我根本无法输入任何内容（终端屏幕截图）。

谁能帮我这个...？

编辑
我找到了一种编辑上述配置文件的方法，但我仍然无法成功运行sudo apt update......
