Upgrade problem with add repositories and ubuntu software center

Question

I want to Update my OS, Ubuntu 14.04 and I have problems with Ubuntu Software Center and add repositories for install more apps.

the command:

sudo add-apt-repository ppa:elementary-os/unstable-upstream
sudo: add-apt-repository: command not found

If you really want to try elementary os, I'd recommend you to install it instead of using a third party repository. — xangua, Jul 23 '15 at 21:27

Simply run

sudo apt-get install software-properties-common

And you'll have add-apt-repository
