用Ubuntu7.10的源直接安裝amsn的話，版本是0.98，這個版本對中文的支持很不完善，例如在聊天的時候，輸入框中打“現在”二字，會只顯示“在”。因此建議用amsn0.97b 版。

步驟：
1.刪除現有的amsn
sudo apt-get remove amsn

2.將現有的Ubuntu7.10的源替換成7.04的源
sudo gedit /etc/apt/sources.list
把文件的內容換成

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

當然，記得備份原來的內容，因為把源換成7.04只是為了裝amsn0.97b，裝完之后還是把源換回7.10好

3.sudo apt-get update

4.sudo apt-get install amsn
如果提示下載一個10.6M的包，解壓后是40.3M的，那應該就對了

5.把源換回7.10
sudo gedit /etc/apt/sources.list
把原來的內容復制進去

6.sudo apt-get update
