ubuntu12.04更新源列表

[size=x-small;] ubuntu是linux操作系统发行的最流行的版本之一，linux操作系统以其优良的特性深受广大用户的喜爱。但是玩惯了windows系统的人们忽然接触linux或多或少会有一些不适应，本文介绍如何ubuntu更新软件源列表。[/size]

[size=x-small;]      ubuntu[/size]里面下载安装软件最方便的方法就是在ubuntu软件中心里面搜索自己需要的软件，然后点击安装，非常方便。也可以在终端里面进行安装，本人推荐是用终端这个工具进行操作因为ubuntu下很多配置都是通过终端进行的，熟悉掌握终端命令是学习linux的必由之路！下面是我总结出来的一系列的安装软件的命令：


安装软件
命令： apt-get install softname1 softname2 softname3……
卸载软件
命令： apt-get remove softname1 softname2 softname3……
卸载并清除配置
命令： apt-get remove --purge softname1
更新软件信息数据库
命令： apt-get update
进行系统升级
命令： apt-get upgrade
搜索软件包
命令： apt-cache search softname1 softname2 softname3……
Deb软件包相关安装与卸载
安装deb软件包
命令： dpkg -i xxx.deb
删除软件包
命令：  dpkg -r xxx.deb
连同配置文件一起删除
命令： dpkg -r --purge xxx.deb
查看软件包信息
命令： dpkg -info xxx.deb
查看文件拷贝详情
命令： dpkg -L xxx.deb
查看系统中已安装软件包信息
命令： dpkg -l
重新配置软件包
命令：  dpkg-reconfigure xxx


   [size=x-small;] 但是这两种方法都存在一个问题就是下载速度的问题。如果你装的是双系统的话，假如你在[/size][size=x-small;]windows[/size]下面有一百来kb/s,但是换了在ubuntu下面可能还不到10kb/s,Ubuntu安装完后。这是因为默认使用的可能是国外的源，速度可能比较慢。现在国内也有很多服务器提供国外源的镜像，可以使得Ubuntu软件包的安装、升级快很多。我举个例子来说明一下：假如我们用的是电信的宽带服务，那我们在电信的服务器上下载资源的话要比在其他服务器上下载同样的资源快一些。这个道理我想就不用过多的解释了。

[size=x-small;]    解决方法：[/size]

[size=x-small;]   其实现在全球各地都设有[/size]ubuntu的软件资源服务地址，源可以在ubuntu的主菜单：系统管理=>软件源配置中图形化的配置。这种方法比较直观，相信大家没什么问题。那么如何在终端里面进行操作呢？其实也没那么难，具体方法如下：


[size=small;]这里备份一下主要是为了以防万一[/size],当然如果你够自信的话也可以省略这一步.
2.sudo gedit /etc/apt/sources.list
[/size]编辑你的源列表，将原来的内容全部删除，添加下面列表中最适合你的源（注意不要全部添加），选择一个最合适你的即可，复制到你的列表中，然后保存列表。[/b]

[size=small;]可以在运行[/size]“sudo apt-get update ”时查看一下错误信息，把不能连接的源删除再重新运行“sudo apt-get update ”。
