Ubuntu下apt

　　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
