ubuntu軟體更新源，更改，可提高更新的速度
更新源方法：
1. 開啟終端。單擊主選單中的“應用程式 - 附件 - 終端”。
2. 修改更新伺服器列表。請在終端中執行下面的兩條命令：
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
還原更新源：
sudo cp /etc/apt/sources.list_backup /etc/apt/sources.list
#備份原來的軟體列表，會要求輸入密碼
sudo gedit /etc/apt/sources.list
#用gedit開啟sources.list檔案
在接下來在開啟的文字編輯器中，把看到的內容全部刪掉，在上面Ubuntu11.04源列表裡選擇一組對於你來說速度最快的更新伺服器列表。貼上到你所看到的視窗中。這裡推薦臺灣源和網易源，更新軟體的速度很快！
4. 關閉文字編輯器。
5. 更新軟體包列表。執行下面的命令：
sudo apt-get update
6. 安裝系統更新
開啟“系統->系統管理->更新管理器”，安裝更新。完成後若系統提示重新啟動，請重新啟動系統。
