因此，您可能已经升级了操作系统，或者对操作系统的支持已结束，这就是问题所在。这些存储库不支持您的操作系统版本。这些存储库仍可在http://old-releases.ubuntu.com/ubuntu。您可以在 /etc/apt/sources.list 中更改它们，将所有出现的http://us.archive.ubuntu.com和http://old-releases.ubuntu.com。
您可以通过终端打开 sources.listsudo nano etc/apt/sources.list
修复该问题的另一种方法：
- 打开“软件和更新”
- 点击“其他软件”
- 选择您收到错误的存储库并删除复选框
- 对 repos 执行同样的操作，你也会得到其他错误
