为什么装不了build-essential?

[嗜血魂K]

hang@hang-laptop:~$ sudo apt-get install build-essential
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package build-essential is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package build-essential has no installation candidate

求助啊?什么原因额...
这个问题阻碍我用ubuntu几个月 了...

源选好了吗？sudo apt-get update过了吗？没遇到过这种问题~

[pllion]

这是依赖问题，用aptitude试试！

请问用这个的话该怎么输入命令呢?
直接把apt-get 替换吗?

[pllion]

代码： 全选

sudo aptitude install build-essential

这个命令会解决一些依赖问题。

系统－系统管理－软件源－－下载自－－其它站点－－选择最佳服务器, 等一段时间后， 然后点这个源， 点选择服务器添加

系统－系统管理－软件源－ubuntu软件，
main universe 什么的 ,在源设置里该打钩的要打钩.

选好后关闭

然后

系统－系统管理---新立德 在新立得中搜索 build-essential ，找到后在新立德中安装。

实在不行,直接下载。

http://packages.ubuntu.com/lucid/build-essential


不要给我说什么什么疯的os, 那是东莞一个叫什么疯的牛人自主研发的os, 人家是开源(开放软件源)的os

那个牛系统很牛，用那个系统的也都是牛人，用那个牛系统的方法不能用在ubuntu 上的， 要不然害我在这里好心发帖，浪费感情。

build-essential。。。请问是什么？

[aerofox]

sudo aptitude update 或 sudo apt-get update 后仍然不行，就把执行这个 update 时的输出信息贴出来看看。
