I'm trying to add a repository on my VPS with Ubuntu 12.04 installed using this command :
sudo add-apt-repository ppa:chris-lea/node.js
But terminal is showing
command not found
Then I've entered the following command to solve the problem
sudo apt-get install software-proprieties-common
But unfortunately I'm getting the following error :
E: Unable to locate package software-proprieties-common
How can I solve this problems?
Now software-properties-common installed, but same problem continues. Please check the screen shot.
