PS：在网上找了一写资料，比如更换下载源，rm /var/cash 之类的都没有解决。

如果你用的是某些小区网络的话，极有可能是网络服务商架设的缓存服务器在作怪。
有些SB搞的缓存服务器只看路径，不看域名，而大部分源的路径是一样的，所以你换个源也没用。

要么去 https://launchpad.net/ubuntu/+archivemirrors 找个路径不同的源，不过这种基本都是国外教育网络的了
要么自己修改一下/etc/apt/sources.list里的源路径，自己在浏览器里打开http://xxxx/ubuntu/看看，如果还有个ubuntu目录的话，就把http://xxxx/ubuntu/这类的改成http://xxxx/ubuntu/ubuntu，后面的ubuntu可以加更多层。163的镜像是没有的，sohu，阿里云的记得都有


另外缓存服务器的缓存标准一是文件大小，二是获取频率，所以也不要更新太频繁
