我正在尝试跟随这些说明
Ubuntu 服务器（推荐）如果尚未安装，请安装 update-manager-core：
sudo apt-get install update-manager-core 启动升级工具：
do-release-upgrade 按照屏幕上的说明进行操作。
将 13.04 的盒子升级到 13.10，但此时我甚至无法update-manager-core安装。有什么想法可以继续吗？如果可以避免的话，我真的不想从头开始重建盒子。
以下是尝试安装的输出update-manager-core
nathan@nasty-vault:~$ sudo apt-get install update-manager-core

答案1
这是因为 13.04 的所有 repo 都已移至存档位置。您甚至需要在执行 do-release-upgrade 之前将它们添加到 repo 中。
