用Ubuntu7.10的源直接安装amsn的话，版本是0.98，这个版本对中文的支持很不完善，例如在聊天的时候，输入框中打“现在”二字，会只显示“在”。因此建议用amsn0.97b 版。
步骤：
1.删除现有的amsn
sudo apt-get remove amsn
2.将现有的Ubuntu7.10的源替换成7.04的源
sudo gedit /etc/apt/sources.list
把文件的内容换成
deb http://Ubuntu.cn99.com/ubuntu/ gutsy main restricted universe multiverse
deb http://Ubuntu.cn99.com/ubuntu/ gutsy-security main restricted universe multiverse
deb http://Ubuntu.cn99.com/ubuntu/ gutsy-updates main restricted universe multiverse
deb http://Ubuntu.cn99.com/ubuntu/ gutsy-proposed main restricted universe multiverse
deb http://Ubuntu.cn99.com/ubuntu/ gutsy-backports main restricted universe multiverse
deb-src http://Ubuntu.cn99.com/ubuntu/ gutsy main restricted universe multiverse
deb-src http://Ubuntu.cn99.com/ubuntu/ gutsy-security main restricted universe multiverse
deb-src http://Ubuntu.cn99.com/ubuntu/ gutsy-updates main restricted universe multiverse
deb-src http://Ubuntu.cn99.com/ubuntu/ gutsy-proposed main restricted universe multiverse
deb-src http://Ubuntu.cn99.com/ubuntu/ gutsy-backports main restricted universe multiverse
deb http://archive.Ubuntu.com/ubuntu/ gutsy multiverse
deb http://Ubuntu.cn99.com/ubuntu-cn/ gutsy main restricted universe multiverse
当然，记得备份原来的内容，因为把源换成7.04只是为了装amsn0.97b，装完之后还是把源换回7.10好
3.sudo apt-get update
4.sudo apt-get install amsn
如果提示下载一个10.6M的包，解压后是40.3M的，那应该就对了
5.把源换回7.10
sudo gedit /etc/apt/sources.list
把原来的内容复制进去
6.sudo apt-get update
