当我更新 apt-get 时，universe repo 需要很长时间才能下载，我通常将速度限制在 130kbps 左右，这可以在不到一分钟的时间内轻松下载约 4mb，但它在每秒 1 字节和 30kpbs 以下之间跳跃（而且我在更新时没有运行任何会占用带宽的东西）。在 lucid 上更新很顺利，花费不到 10 秒，为什么现在需要大约 10 分钟……

如果有人能帮忙，我会非常感激
答案1
发生这种情况是因为每个文件夹中的 Packages.gz 都很大并且现在经常更改。发布后，它将与 Lucid 相同。另外，尝试为您找到最快的服务器（在镜像选择对话框中）。
答案2
我相信造成这种情况的原因比 Extender 所说的要多一些。如果您查看终端的输出，您会看到以下几条条目：
Hit http://country.archive.ubuntu.com maverick/universe Sources
在开发期间，“universe”部分（还有“restricted”、“multiverse”和“main”部分）中的每个软件包更新都需要更改此文件。但是发布后，这些文件不再更新，相反，您将看到来自以下位置的更新：
Hit http://country.archive.ubuntu.com maverick-updates/universe Sources
因为只有相当小比例的软件包在发布后进行更新，所以该文件比在发布时发布并在开发期间使用的文件小得多。
现在 Ubuntu (Maverick) 10.10 已经发布，更新速度应该会更快。
