How to Update Ubuntu Linux

While still in the terminal window, run sudo apt-get update. You will be prompted for your root password (enter it). Caution: Using "sudo" allows you to have root/administrator privilages, check what you type before hitting enter as serious damage can be done as root/adminstrator. All update does is update the lists of software from your repository. Some distros do this automatically.

After apt-get is done, run sudo apt-get upgrade. Again, enter your password and wait 2-3 seconds. You will see a list of packages which should be installed to upgrade. You can upgrade individual packages as follows:

• sudo apt-get upgrade firefox

You will be asked if you want to upgrade those packages, if yes, type 'Y' and hit enter. If you don't want to upgrade then type 'n' and press enter to abort.

Apt-get will now download and install all of these packages. Bear in mind that this can be a very large download, and will take a considerable time depending on your internet connection speed.

You can update from a CD too.
