Ubuntu14.04下安装Hadoop2.4.0 （单机模式）

三、安装ssh

sudo apt-get install openssh-server

 E:Could not open lock file /var/lib/dpkg/lock - open (13:Permission denied)

    E:Unable to lock the administration directory (/var/lib/dpkg/),are you root? 

    解决方案：

    sudo rm -rf /var/lib/dpkg/lock

    sudo rm -rf /var/cache/apt/archives/lock

    sudo apt-get update

    最后运行：sudo dpkg --configure -a  重新配置（系统会提醒） 。
