trying to install libncurses dev package for ubuntu 14.04 [duplicate]

I am trying to install libncurses for Ubuntu 14.04. But, it is showing the following error:

root@sharwariDell:/usr/src# sudo apt-get install libncurses5-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libncurses5-dev

The package libncurses5-dev is available on base:main repository for Ubuntu 14.04.

So, make sure you have enable main & universe repositories:

The main component contains applications that are free software, can be freely redistributed and are fully supported by the Ubuntu team. & The universe component is a snapshot of the free, open-source, and Linux world.

If you choose command-line, following command may help you:

sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe"
sudo apt-get update
sudo apt-get install libncurses5-dev
