Ubuntu 12.10 Quantal Quetzal Has Reached EOL. Upgrade To Ubuntu 14.04 Or Ubuntu 13.10

Hello Linux Geeksters. As you may know, Ubuntu 12.10 Quantal Quetzal has reached and of life (EOL) yesterday, meaning that no more security updates will be performed by Canonical and the LaunchPad PPAs will not receive any new packages for Ubuntu 12.10.

Due to the fact that Ubuntu 13.04 was the first system with only 6 months support, and Ubuntu 12.10 reached EOL after Ubuntu 13.04.

Because the support for Ubuntu 13.10 Saucy Salamander ends in July 2014, it is advised that you upgrade from Ubuntu 12.10 to Ubuntu 13.10 and next, to Ubuntu 14.04 Trusty Tahr LTS.

In this article I will show you how to upgrade from Ubuntu 12.10 Quantal Quetzal to Ubuntu 13.10 Saucy Salamander and next to Ubuntu 14.04 Trusty Tahr, via the command-line interface.

How to upgrade from Ubuntu 12.10 to Ubuntu 13.10. Install the update-manager-core tool, if it is not already installed:

$ sudo apt-get install update-manager-core

Next, start the upgrade process and follow the graphical instructions:

How to upgrade from Ubuntu 13.10 to Ubuntu 14.04 LTS. Just repeat the process and follow the installation wizzard:

$ sudo apt-get install update-manager-core
$ sudo do-release-upgrade
