    You don't need to change it but upgrade it. Here's a [link](http://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release) as to how to do that. – Raphael Feb 10 '16 at 05:45

Ubuntu 14.10 is an obsolete version and if you want to use, update & install packages then you need to change its repository.

You can do this in following way:

Open Terminal & run:

sudo gedit /etc/apt/sources.list

Replace url in.archive.ubuntu.com and security.ubuntu.com with old-releases.ubuntu.com

save and close it.

Now run sudo apt-get update and after then install any packages you want to install.
