Ubuntu ARM版使用Debian的源安裝軟體

目前主要的問題是Ubuntu的ARM源中預編譯的軟體太少，比如clisp就沒有。

所以在更新或安裝時 常常會有問題

apt-get update

.....

因為debian支持arm已經很多年了，所以可以考慮使用debian的源。

配置的步驟如下：

1. 導入debian的公開金鑰環

#wget http://ftp-master.debian.org/keys/archive-key-6.0.asc
#gpg --import archive-key-6.0.asc
#gpg --fingerprint 473041FA
#gpg --armor --export 473041FA | sudo apt-key add -

2. 添加debian源
#sudo vim /etc/apt/sources.list
在最後添加

deb http://http.us.debian.org/debian testing main non-free contrib
deb-src http://http.us.debian.org/debian testing main

3. 更新資料庫
#sudo apt-get clean
#sudo apt-get update

現在就可以安裝需要的軟體了。需要注意的是這種方法並不能保證系統的穩定性。
