[问题]求助！从7.04升级到7.10时出错

[miniphoon]

通过更新管理器升级时老是出现“升级时出错”

请问该如何解决？修改软件源吗？

更换软件源不行，从alterlate光盘启动出错：
无法计算升级

在计算升级时遇到一个无法解决的问题。

请汇报这个有关 'update-manager' 的错误，并且将 /var/log/dist-upgrade/ 中的文件包含在错误报告中。
删除wine也不行。
是bug吗？

升级时出错
升级时候出错。这通常是一些网络问题，请检查你的网络连接后再试。

应该不是网络问题吧？？

把源文件的feisty 改成 gutsy

代码： 全选

sudo apt-get update
sudo apt-get dist-upgrade

[forrid]

feisty的源？是不是应该换成gusty的？

[miniphoon]

把源文件的feisty 改成 gutsy

代码： 全选

sudo apt-get update

更换源文件也不行啊！都是获取文件失败！！
到底是什么原因啊？？
