从 12.04 升级到 13.10 遇到问题

我不知道有更新计划询问我的约会问题，但我有点懒。无论如何，我有一个红色三角形，里面有一个感叹号，如果我点击它，它会告诉我

The update information is outdated. This maybe caused by network problems or by a repository that is no longer available. Please update manually by clicking on this icon and then selecting 'check for updates' and check if some of the listed repositories fail."

我照做了，并从更新管理器中获取了此信息

E:Some index files failed to download. They have been ignored, or old ones used instead.

我想修复这个问题并更新到较新版本的 Ubuntu。
