![从 12.04 升级到 13.10 遇到问题](https://linux22.com/image/844652/%E4%BB%8E%2012.04%20%E5%8D%87%E7%BA%A7%E5%88%B0%2013.10%20%E9%81%87%E5%88%B0%E9%97%AE%E9%A2%98.png)
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The update information is outdated.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

我想修复这个问题并更新到较新版本的 Ubuntu。
