1、更新軟件包列表并安裝apt-spy
#apt-get install apt-spy
2、自動下載列表并使用apt-spy測試最快的源
#apt-spy update
#apt-spy -d stable -a Asia
3、查看生成的配置文件，里面是最快的源
#cat /etc/apt/sources.list.d/apt-spy.list
#cp /etc/apt/sources.list.d/apt-spy.list /etc/apt/sources.list
#apt-get update
幾個比較快的
deb ftp://ftp.cn.debian.org/debian/ stable main #contrib non-free
deb http://mirrors.163.com/debian/ stable main #contrib non-free
deb-src http://mirrors.163.com/debian/ stable main #contrib non-free
deb http://security.debian.org/ stable/updates main
4、由于依賴關(guān)系安裝失敗的問題
由于ubuntu/debian軟件庫中有時候不同的庫更新速度不一致，apt-get 出出現(xiàn)如下的錯誤提示
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libssl-dev: Depends: libssl0.9.8 (= 0.9.8k-7ubuntu8) but 0.9.8k-7ubuntu8.5 is to be installed
這個時候應(yīng)該請令一個工具出馬了："aptitude"
使用這個工具，當(dāng)某個庫依賴的庫與當(dāng)前版本不一致時，aptitude 會嘗試降級當(dāng)前這個庫的版本，同時解決降級這個庫對其它軟件的依賴性的影響， 最終成功安裝apt-get 沒法安裝的軟件
如：
#aptitude install vim-gnome
