apt 错误消息 ubuntu virtualbox guest

我刚刚在 Virtual Box Mac 上安装了 Ubuntu（最小安装）。我无法通过 apt 安装任何软件。它显示错误消息

E: Unable to locate package cmatrix

我以前遇到过这个问题，后来通过更新 snapd 解决了（我删除了虚拟机）。现在我尝试更新 snapd 时，它出现了错误。然后错误消失了。但什么都没变。我也试过了，sudo apt update但失败了

E: some index files failed to download

编辑： 我试过了如何恢复默认存储库？ 但它什么也没做

以下是新的完整错误信息

注意：我之前做过这个更改，但似乎没有保存，因为它回到了nz.archive.ubuntu.com

我修好了它，我真是太蠢了。所以我无法访问该网站，然后我修好了它，然后轰隆隆

我很抱歉造成您的不便
