I want to upgrade my Ubuntu to the latest version.My ubuntu release when i run the lsb_release -a is:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:   trusty

But i think this is not the latest version of the Ubuntu released on the Ubuntu site.when i exec sudo update-manager -di get nothing to update! How can i upgrade my system to the latest version without losing any application or data

    14.04 is the latest LTS version. It is not a brilliant idea to upgrade to a non-LTS version. – Pilot6 Oct 25 '15 at 13:53

To upgrade to the latest version you would first have to upgrade to 14.10 and then to 15.04 !

This probably may result in some issues - you should consider a clean install of Ubuntu 15.10.

... and by the way ... it will be much faster ...
