Ubuntu12.10 更換源

本文參考：

每次更新都有更換更新源，其實更新源位址不必上網找，直接自己更改就可以了。更新源的位址基本上是這樣的：

deb http://ubuntu.srt.cn/ubuntu/ oneiric main universe restricted multiverse

這個是Ubuntu 11.10的更新源位址，其中 oneiric就是ubuntu 11.10的開發代号，是以我們隻需要将電腦中的更新源清單裡的開發代号替換為Ubuntu 12.04的開發代号就可以了，用ctrl+F查找出來全部替換就可以了。是以以後再換版本就不用自己上網搜尋更新源了。

Ubuntu 12.04的開發代号是Precise Pangolin，譯為精确的穿山甲。是以隻需将oneiric替換為precise即可

1、首先備份Ubuntu 11.10源清單

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup （備份下目前的源清單，有備無患嘛）

2、修改更新源

sudo gedit /etc/apt/sources.list （打開Ubuntu 11.10源清單檔案）

3、用ctrl+F查找所有的oneiric，然後全部替換為precise

4、通知ubuntu啟用新的更新源 sudo apt-get update

//當然如果你比較懶，或者是全新安裝的ubuntu，那你可以直接把下面的代碼複制到sources.list中

//教育網源

如果你是在校大學生，可以使用校園網/教育網，就是用教育網的資源吧，中科大，蘭大、廈門大學都有很多資源，尤其是支援ipv6的，那更新速度就按兆算了。

最終我用的網易的源，速度300K/s以上，還挺快的。

後來我才知道不用指令的方式也可一更改源。

打開ubuntu軟體中心 ，單擊編輯-》軟體源，在“下載下傳自”後面選擇“其他站點”，然後彈出來的視窗中，-》選擇最佳的伺服器，之後等着，最後輸入使用者密碼點授權就可以了。

繞了一大圈，真是的。
