最近刚开始接触Linux，在虚拟机中装了个Ubuntu，当前的版本是Ubuntu 11.10，装好后自然少不了安装一些软件，在设置了软件的源后，就开始了 sudo apt-get install，结果出现了下面的Unable to locate package错误：
- letuknowit@ubuntu:~$ sudo apt-get install mysql-server mysql-client
- [sudo] password for letuknowit:
- Reading package lists… Done
- Building dependency tree
- Reading state information… Done
- E: Unable to locate package mysql-server
- E: Unable to locate package mysql-client
- letuknowit@ubuntu:~$
这叫一个郁闷啊，出师不利，不带这么吓唬刚玩Ubuntu的小朋友吧~于是赶紧找资料，又回顾下前面的操作，最后发现问题出在执行sudo apt-get install之前更换了软件源，但是却忘了update下了，于是执行下面的命令：
- sudo apt-get update
等上面命令执行完后，再执行sudo apt-get install就可以了！其实错误信息已经很明确了，Unable to locate packet就是无法找到包嘛，那还不赶紧sudo apt-get update下！

thanks. it’s helpful to me:)
有时间应该看看。。到底是啥区别。。
现在问题是 ：sudo apt-get update 执行这个 也报错 E: Unable to locate package 。如何解决？
确认下包的名字是否正确
我这也是这样的，最后怎么解决的啊。。。。

sudo apt-get update
sudo apt-get upgrade
之后，还是会出现那个问题，咋办。还是没法安装。
