用apt-get安装任何软件都出错！

[fatalerr]

今天发现在运行apt-get upgrade是出错如下。请教各位该如何解决？根据系统的提示，要用命令：apt-get -f install来解决，但我运行该命令后，系统提示我将会删除一大堆软件，我没敢试，先问一下大家，是应该这样处理吗？

我记得问题是在前几天我装一个deb包后发生的，当时装这个deb包因为缺少其他包的原因没有装成功，提示要求的包虽然系统上有，但版本不对。后来我就没再装，再后来用apt-get的时候就出问题了。

刚才又试了一下，不但upgrade会出下面的错，安装别的软件也会出同样的提示！

搜索了一下，看来遇到类似的问题挺多的，但要么就没任何信息，要么就是只在论坛上留个“已解决”，没一个说出解决方法来的！郁闷！

有人说可能是apt源的问题，我用的是官方的源啊。详细信息如下：

一个字，删……

把系统提示的要删除的删除掉

[fatalerr]

搞定了。
是因为手动安装了一些库文件，版本不兼容引起的。后来使用了aptitude来将这些库文件降级。降级后恢复正常。
