我的10.04装好后，这将近半年的时间一直有包的以来性问题，譬如我要装个libqt4-opengl,
然后就提示错误：

sudo apt-get install libqt4-opengl

这个错误我觉得很奇怪，其实他要求4.6.2的libqtcore4，而且我也有4.6.2, 也就是说软件包是没有问题。

唯一的区别就是在ubuntu5和ubuntu5.3上，其实这个检查是没有必要的，我现在什么软件也装不了，非常郁闷，求帮助。

补充一下：我用的是官方的源：
deb http://archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu/ lucid main restricted universe multiverse

问题解决了，我重新找了个完整的源，update了一下就好了。

好久没上这个论坛了，想不到上一下就解决了我的问题。

论坛是个好地方
