Ubuntu: Upgrade Ubuntu 14.04 to 16.04 using a bootable USB stick


I use Ubuntu 14.04 and I want to upgrade my version of Ubuntu to the latest 16.04 LTS release. One way to do that is using the update-manager. Is there any other way to do it ? Like using a bootable USB stick with 16.04 on it.


Go to your Unity Dash, locate "Startup creator" and create a bootable installation USB disk using it. You will of course first download the *.iso image. Make sure that your USB is recognized when you plug it in, so that the creator knows which drive to use.

Then boot your computer using the USB.


Upgrade your system

First you have to check if there is a new version of Ubuntu

sudo do-release-upgrade -d   

Wait for the system to finish installing , it takes time patience is needed :-) .. When it finishes reboot Ubuntu

Verify all packages are up to date

sudo apt update  sudo apt full-upgrade  

Clear the cache

You don't want to keep that 1 or 2 Go of dependencies slowing down your system of course

sudo apt-get clean  sudo apt-get autoclean  sudo apt-get autoremove  

Verify your version

lsb_release -a  

You should get Ubuntu 16.04 LTS Xenial Xerius as output
