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
