   ------------------------------------------------------------------

2.  

   在此说明配置源的方法：

   很简单，把源地址写进 /etc/apt/sources.list 就可以了。

   可以用 # 注释。

   推荐163，搜狐等源。

3.  

   sources.list 写好后，需要更新一下。使用如下命令：

   apt-get update

   如果提醒你需要导入密钥，则：

   gpg --keyserver <KeyServer> --recv <公钥签名>gpg --export --armor <公钥签名> | sudo apt-key add -

     其中：

     <KeyServer>，key服务器，可以填 keyserver.ubuntu.com ，当然也可以是   其他的喽。

     公钥签名会在update的提示中说明的。

   也可是使用如下形式：

   apt-key adv --keyserver <KeyServer> --recv-keys <公钥签名>

4. 5

   经过以上步骤，源已经更新完毕，可以试着使用新源更新一下软件库喽：

   apt-get upgrade
