I am a new user here and I wanted to know if I could update from Ubuntu 14.04 to later versions without reinstalling Ubuntu to my system?

Edit /etc/update-manager/release-upgrades and change:

[DEFAULT]
Prompt=lts

to:

[DEFAULT]
Prompt=normal

and then:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

and finally:

do-release-upgrade

If it tells you command not found for do-release-upgrade, install it with:

sudo apt-get install update-manager-core
