Hello Linux Geeksters. As you may know, Ubuntu 12.10 Quantal Quetzal is a non-LTS system and so, it will reach EOL in April 2014. The final date for the Ubuntu 12.10 EOL hasn’t been set yet, but it will probably be after the big April 17 launch of Ubuntu 14.04 LTS.
For now, the final EOL date for Ubuntu 12.10 is not know yet, but most likely it will be after the 17th of April, when Ubuntu 14.04 gets released.
Upgrading from Ubuntu 12.10 Quantal Quetzal to Ubuntu 14.04 Trusty Tahr can be done easily via terminal. All you have to do is:
Just 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:
$ sudo do-release-upgrade
