As the Ubuntu 12.04 beta is out I thought I should give it a try. Currently I am using Ubuntu 11.04. So it is very simple task to Upgrade my current version to Ubuntu 12.04.
Before doing so I was having 3 options
Option 1 – Download ISO image from the ubuntu website and burn that into CD. Boot the cd and upgrade while installing into your machine which have earlier version of Ubuntu.
Option 2 – Make a Bootable flash drive to upgrade.
Option 3 – Use Update Manager.
As the easiest method I started upgrading my current OS using option 3.
Step 1 : Open a command propmt and run following commands
sudo apt-get update sudo apt-get install update
Step 2 : Now start Update Manager using following command
sudo update-manager -d
Step 5 : For downloading and upgrading my machine it took 45 minutes. The time limit depends on your internet connection.
