E: Dynamic MMap ran out of room
E: 处理 qt3-assistant (NewVersion1)时出错
E: Problem with MergeList /var/lib/apt/lists/ubuntu.cn99.com_ubuntu_dists_dapper-security_universe_binary-i386_Packages
E: 无法解析或打开软件包列表或状态文件。

没有软件包列表。
把源更改成以下后就出现这个问题了。

新手上路请多多关照。

搞定了，原来我把edgy的源加上去了，太贪心了 。

不过到现在还不知道edgy和dapper，到底是什么意思？有什么区别？
哪位先驱可以告诉我。
