連到機器以後

先備份一下原來的 sources.list

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

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

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

如果有人在這一步驟出現問題

那是因為預設並沒有裝vim這一套編輯器

可以改成vi或者是gedit

或者參考底下這文章來安裝 Vim

[ubuntu] VIM – 好用的文字編輯器

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
