问题：

  在通过apt-get安装内存测试工具lmbench的时候，出现如下错误：

apt-get install lmbench

Reading package lists... Done

Building dependency tree       

Reading state information... Done

You might want to run 'apt-get -f install' to correct these:

The following packages have unmet dependencies:

 mpt-status : Depends: daemon but it is not going to be 


installed

              Depends: mailx

E: Unmet dependencies. Try 'apt-get -f install' with no packages 


(or specify a solution).


诊断：

  通过资料查找，发现可能是安装的其他软件包不兼容导致了，同时根据提示需要执行“apt-get  -f install ”来卸载之前的冲突包。

 还有个命令是：aptitude -f install


解决：

  执行如下命令：

aptitude -f install
