我正在尝试按照以下指南从 13.04 升级到 13.10: http://www.unixmen.com/upgrade-ubuntu-13-04-raring-ubuntu-13-10-saucy-salamander/

答案1

我已经apt-cacher安装好了。

https://help.ubuntu.com/community/Apt-Cacher-Server

删除或编辑您添加的代理文件/etc/apt/apt.conf.d/ 以绕过apt-cacher

答案2

我也遇到了“无法获取”的问题。将“软件和更新”中的软件源改回“主服务器”服务器,而不是特定国家/地区的“国家/地区服务器”,升级就可以继续了。
