Ubuntu14.04更新源

Ubuntu14.04默认的源都是国外的，因此咱们下载东西十分的慢，更新一下中国源，让下载速度能够更快，这里有两种方法更新源的方法，一种是图形界面操做，另外一种是命令操做。

工具/原料

• Ubuntu14.04

方法一：图形界面操做更新源

1. 1

   点击右上角的”搜索“图标，在搜索框中输入update，在显示的应用列表中，点击”Software&Updates（软件&更新）“。

2. 2

   在 弹出的”Software&Updates“窗口中，选择”Ubuntu Software“，你能够看到”Download from（下载源）“是”Server for United States(美国服务器)“。点击”Server for United States“下拉菜单，选择”Other...（其余）“。

3. 3

   在 弹出”Choose a Download Server（选择下载服务器）“窗口中向上拉，找到China（中国）,而后，选择中国的服务器，这里能够选择教育源，网易、阿里等等。（我在这里选的 是163（网易）的），而后点击”Choose Server（选择服务）“按钮。

4. 4

   而后，弹出”Authenticate（认证）“窗口，输入系统密码（ubuntu上因为安全性安装软件，须要输入密码），而后点击”Authenticate（认证）“按钮。

5. 5

   此时，你会发现”Software&Updates“窗口中的”Download from（下载源）“已经变成你设置的中国源。点击”Close(关闭)“按钮。

6. 6

   而后，会弹出一个提示,大概意思是”安装软件和更新添加的源或修改源，必需要从新加载可用软件的信息“，点击”Reload（重载）“按钮。进入”Updating cache(更新缓存)“界面，等待更新完事后，下载源就真正变成中国的了。之后下载东西就更快了。

   END

方法/步骤2
