【求助】ubuntu下无法安装c complier

lyqnnnn

打算安装compiz，按照forum.compiz.org上的步骤，提示缺少c complier,
于是apt－get install basic-essential,但返回的结果是
        环境是ubuntu 6。06

想要安装basic－essential,但是返回的信息是：

The following packages have unmet dependencies:
build-essential:
Depends: libc6-dev but it is not going to be installed orlibc-dev
Depends: g++ (>= 4:4.0) but it is not going to be installed
E: Broken packages

请教高手该如何解决（原以为是源里的packages坏了，但换了其它的源还是同样的提示）
