轉眼間 Ubuntu 到了發行 LTS 版本的時間了

這次更新的是 Ubuntu 12.04 LTS (Precise Pangolin)

下載完以後要先做得事情就是…

換 sources.list

另外 Ubuntu 12.04 LTS 又把 Vim 加進來了

要用 Vim 去修改的話

請按照下面步驟

1.

首先先備份原始的sources.list

避免我們改爛了沒有可以還原的檔案

sudo cp -a /etc/apt/sources.list /etc/apt/sources.list.bak

2.

之後是把原本的檔案給刪除

所以下底下這指令

sudo rm -rf /etc/apt/sources.list

3.

刪除以後

當然要建立該檔案阿

不然就沒有辦法更新了

所以下底下這指令

sudo vim /etc/apt/sources.list

4.

進到畫面以後

按下鍵盤上面的 Insert 鍵 或者是 i

就進入編輯模式

將底下的東西一字不漏的貼上
