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
