Vim installation in Ubuntu 14.04

I am unable to install Vim and need help. I've tried the following:

root@cbitlab1:/home/cbitlib1# sudo -s
root@cbitlab1:/home/cbitlib1# apt-get install vim

Package vim 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 ‘vim’ has no installation candidate

How do I fix this - I'm on 14.04.

To make sure you have the latest sources.list

sudo apt-get update

then run:

sudo apt-get install vim

Vim is pre-installed in Linux based OS. For Ubuntu its minimal version is pre-installed.

vim.tiny

You can create alias to run it as vim

alias vim=vim.tiny

To make that alias permanent,

gedit ~/.bashrc

Add alias vim=vim.tiny line in .bashrc file.
