樹莓派 添加國內源

E: Package <packagename> has no installation candidate錯誤，因而便開始google，尋找緣由。但苦苦追尋，能查到的都是
一些叫咱們輸入指令的語句  如sudo apt-get update等之類的命令，但該命令無論用。這是由於在咱們的/etc/apt/sources.list
文件下，擁有的是隻是一些系統初裝的源，後期的一些源仍是得本身添加的，否則網上的不少資源包都是沒法使用的。下面我就貼上
我在網站上找到的各類源。

sources.list（源）

位置：/etc/apt/sources.list

（註釋：deb表明的是咱們須要的deb軟件包，deb-src 是指下載源代碼得指示。以後是包的來源地址，再在後面是系統的標記。以後的main表明的是主要軟件包，universe是不被官方支持的自由軟件。)

 

  如何更改源呢？爲了方便，首先安裝vim

sudo apt-get update
sudo apt-get install vim

1、首先備份Ubuntu 8.04 的當前更新源列表（以備不測）

      sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup （備份下當前的源列表）

二、修改更新源
      sudo vim /etc/apt/sources.list 
3、在裏面我選擇在後面添加源；

四、通知Ubuntu 11.10 啓用新的更新源
     sudo apt-get update

 

 

個人終端命令如圖：

root@ubuntu：~# sudo apt-get update
