ubuntu12.04怎么设置软件更新源

你好，操作如下： buntu的源用来apt-get install会根据源中的url去查找对应的软件（guess），所以源的配置决定着你更新软件的速度，甚至能否找到对应的命令（我就是在安装一个命令发现404的时候才想起来更新的）。 当前的系统的源的信息保存在/etc/apt/sources.list文件中，当前系统的源如下（这个应该是ubuntu 12默认使用的）： ? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 terryu@ubuntu:~/workplace//trunk/tbsys$ grep -v "^#" /etc/apt/sources.list | grep -v "^$" deb /ubuntu/ precise main restricted deb-src /ubuntu/ precise main restricted deb /ubuntu/ precise-updates main restricted deb-src /ubuntu/ precise-updates main restricted deb /ubuntu/ precise universe deb-src /ubuntu/ precise universe deb /ubuntu/ precise-updates universe deb-src /ubuntu/ precise-updates universe deb /ubuntu/ precise multiverse deb-src /ubuntu/ precise multiverse deb /ubuntu/ precise-updates multiverse deb-src /ubuntu/ precise-updates multiverse deb /ubuntu/ precise-backports main restricted universe multiverse deb-src /ubuntu/ precise-backports main restricted universe multiverse deb /ubuntu precise-security main restricted deb-src /ubuntu precise-security main restricted deb /ubuntu precise-security universe deb-src /ubuntu precise-security universe deb /ubuntu precise-security multiverse deb-src /ubuntu precise-security multiverse 学到grep新的使用方式：^用来匹配一行的开始，-v表示不包含指定字符串的作为满足条件的行，$用来匹配一行的结尾

ubuntu更新软件源需要联网吗

当然要联网。ubuntu是基于网络的操作系统。 每当要进行系统的更新、软件的安装与更新，都要联网访问软件源。

ubuntu如何更新源

更新源不难，在终端中输入 sudo apt-get update就可以了。前提是你在 系统－系统管理－软件源－第三方软件中加了源的网址。可以在这里找到源地址/ic.php?t=38756

你的显卡是ATI还是NVIDA呢？把安装盘放入光驱，然后 系统－系统管理－受限驱动管理器，把受限的显卡打勾。在“系统－系统管理－新立得软件包管理器”中以piz”，“xgl”为关键词搜索，分别安装下面两个软件包：
compizconfig-settings-manager
xserver-xgl
安装完后重启。 
在“系统－首选项－外观－视觉效果”中选择自定义，并单击“gtk首选项”其效果等同于在“系统－首选项”点击 “Advanced  Effects Settings”，弹出piz config 设置管理器”对话框，将“桌面立方体”，“旋转立方体”，“立方体倒映”选中。然后按Ctrl＋Alt，同时点击鼠标左键并移动，怎么样，出现立方体了吧。其它的功能自己摸索吧，但是不要选的太多，各个特效插件之间是有冲突的，我曾因为选的特效太多而重装了两遍系统。网上很多文章介绍各个插件的作用的，自己搜吧。
ubuntu12.04怎么改变更新源
1 、首先备份 Ubuntu12.04 源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup  （备份下当前的源列表）
2 、修改更新源
sudo gedit /etc/apt/sources.list  （打开 Ubuntu 12.04 源列表文件）
3 、把里面的列表替换成下面的列表

教育网源
如果你是在校大学生，可以使用校园网 / 教育网，就是用教育网的资源吧，尤其是支持 ipv6 的，那更新速度就按兆算了。

ubuntu 14.1 怎么设置更新源
1、首先打开终端，用root登陆。
2、切换到/etc/apt/目录下，执行：cd /apt/get/，如图：

3、将里面的sources.list复制一下，为了安全。如图：

4、接下来就是用vim 打开 sources.list，将里面的原有的内容删除，然后添加如下内容：

5、最后执行：apt-get update就好了。如图：
ubuntu怎么换源
可能是教育网原因
改源:
/etc/apt/sources.list
去wiki找教育网源

改ip:
/work/interfaces
man 5 interfaces或者google,看interfaces文件写法
