UTM 中没有互联网连接（Ubuntu 18.04）

我一直在 M1 上通过 UTM 使用 Ubuntu 20.04，最近由于需要它，我安装了 Ubuntu 18.04。

问题是，虽然我在 20.04 上没有遇到网络连接问题，但在 18.04 上却没有网络连接。我发现一个有趣的事情是，互联网似乎在“控制台界面”下工作，因为我可以sudo apt update毫无问题地运行，但如果我在“图形界面”下运行它，错误代码如下：

Err:2 http://kr .ports.ubuntu.com/ubuntu-ports bionic-updates InRelease

首先我尝试sudo apt update通过在和中分别添加dns-nameservers 8.8.8.8 8.8.4.4和来解决上述错误，但仍然无法解决问题。nameserver 8.8.8.8 nameserver 8.8.4.4$ sudo nano /etc/network/interfaces$ vi /etc/resolv.conf

然后我检查了lshw -C network18.04 和 20.04，输出几乎相同，只是18.04 的输出最后一行ip缺少 和link=no而不是。yes
