在关闭我的问题（因为重复）之前，我想说我已经看过其他类似的问题，但没有找到任何合适的答案:(。
我有一个干净的 Ubuntu 10.10 设置，我正尝试通过 apt-get 命令安装软件包。但我做不到 - 显示 E：无法找到软件包错误。我正在尝试以下命令：
sudo apt-get install build-essential，sudo apt-get insatll update 等。
我查看了另一个问题，发现它依赖于 sources.list 文件 - 因此我发布了其内容：

有人能帮帮我吗？谢谢！！
答案1
首先，Ubuntu 10.10 目前已完全不再受支持。这是一个旧版本的 Ubuntu，最好不要使用 - 您将不再获得任何安全更新。
其次
sudo apt-get install update
确实会给你一个错误（因为你告诉 apt 安装不存在的包“update”）。你想要做的是
sudo apt-get update
sudo apt-get upgrade
这将从存储库更新软件包列表（但由于 Ubuntu 10.10 已过时，因此可能没有太多需要更新的内容），并将安装在您的系统中找到的任何更新。
您可能还想在 Synaptic 中查看是否有要安装的软件包。如果不起作用，您可能需要更改下载镜像。为此，请转到更新管理器，点击“设置”，然后转到“Ubuntu 软件”选项卡并更改“下载自”框。如果您随后单击“其他”，则可以选择地球上的任何服务器。
答案2
您需要更新以下条目的来源列表
http://il.archive.ubuntu.com/ubuntu/
现在应该指向
http://old-releases.ubuntu.com/ubuntu/
对所有实例执行相同操作。
请记住，虽然您可以通过这种方式安装应用程序，但它们将是几年前的版本。
