utuntu 10里的软件中心，任何软件都无法安装了

[cysk_zhang]

试用了下ubuntu10，觉得挺不错，特别是里面的软件中心，很方便。

但是安装了一些软件之后，不知道从什么时候开始，软件中心就傻掉了。
安装任何软件都会报：

需要安装不能信任的软件包
这个动作需要从没有授权的软件源来安装软件包。

很崩溃啊，有人知道这是怎么回事，如何解决吗？

没有授权的软件源

很明显。换源

[cysk_zhang]

哎，可是之前我没有动过源啊。。。

真的是所有的都无法安装了，试了十几个了都是报同样的错误。

后来我把之前装上的一个软件包卸了，然后重装，也是报同样的错误。
下面是我的源的配置：

代码： 全选

在软件源中，下载点，选择最佳服务器，使用搜索到的源，问题就ok了！

ls正解

在安装GVIM是也遇到了这个问题，把软件源里的“中国”改成了“main”，就可以安装了

我也遇到同样的问题，按照5楼说的方法 还了一个源就可以了。

非常感谢5楼的。
