今天遇到一ubuntu，别人刚装的，我下载了ncftp，准备从其它地方把文件搬过来，把 ncftp下载回来解压缩，照原来的安装方式进行安装，执行：
make install
提示我找不到make命令：
The program 'make' is currently not installed. You can install it by typing:
apt-get install make
我尝试apt-get install make进行安装，可是提示：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package make is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'make' has no installation candidate
尝试通过关键词：
The program 'make' is currently not installed
及
Package make is not available, but is referred to by another package
进行GOOGLE，基本上没有人碰到我这样的情况，找不到相应的答案，最终求助高手，通过以下的方式进行搞定：
1、先放入UBUNTU安装盘到光盘中；
2、再按顺序执行以下的命令：
sudo apt-cdrom add
sudo apt-get update
sudo apt-get install build-essential
就可以搞定了。
