zz无法初始化前端界面Dialog工具问题解决

K. Feng. (2015, Sep 18). 无法初始化前端界面Dialog工具问题解决 [Online]. Available:

　　错误提示：

debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)
debconf: falling back to frontend: Readline

　　解决方法：利用apt-get重新安装相关组件：

apt-get install dialog

　　ReadyNas也是精简了不少东西啊。。。
