Ubuntu14.04更新源

Ubuntu14.04默認的源都是國外的，因此咱們下載東西十分的慢，更新一下中國源，讓下載速度能夠更快，這裏有兩種方法更新源的方法，一種是圖形界面操做，另外一種是命令操做。

工具/原料

• Ubuntu14.04

方法一：圖形界面操做更新源

1. 1

   點擊右上角的」搜索「圖標，在搜索框中輸入update，在顯示的應用列表中，點擊」Software&Updates（軟件&更新）「。

2. 2

   在 彈出的」Software&Updates「窗口中，選擇」Ubuntu Software「，你能夠看到」Download from（下載源）「是」Server for United States(美國服務器)「。點擊」Server for United States「下拉菜單，選擇」Other...（其餘）「。

3. 3

   在 彈出」Choose a Download Server（選擇下載服務器）「窗口中向上拉，找到China（中國）,而後，選擇中國的服務器，這裏能夠選擇教育源，網易、阿里等等。（我在這裏選的 是163（網易）的），而後點擊」Choose Server（選擇服務）「按鈕。

4. 4

   而後，彈出」Authenticate（認證）「窗口，輸入系統密碼（ubuntu上因爲安全性安裝軟件，須要輸入密碼），而後點擊」Authenticate（認證）「按鈕。

5. 5

   此時，你會發現」Software&Updates「窗口中的」Download from（下載源）「已經變成你設置的中國源。點擊」Close(關閉)「按鈕。

6. 6

   而後，會彈出一個提示,大概意思是」安裝軟件和更新添加的源或修改源，必需要從新加載可用軟件的信息「，點擊」Reload（重載）「按鈕。進入」Updating cache(更新緩存)「界面，等待更新完事後，下載源就真正變成中國的了。之後下載東西就更快了。

   END
