Hello Linux Geeksters. As you may already know, Ubuntu 13.10 Saucy Salamander has reached its end of life (EOL) yesterday, meaning that the system (and its derivatives) will not receive any updates and LaunchPad does not permit users to add updated packages for Ubuntu 13.10.
Until October 2014, when Ubuntu 14.10 Utopic Unicorn gets released, Ubuntu 12.04 LTS and Ubuntu 14.04 LTS are the only two desktop versions of Ubuntu supported.
In this article I will show you how to upgrade from Ubuntu 13.10 Saucy Salamander to Ubuntu 14.04 Trusty Tahr and from Linux Mint 16 Petra to Linux Mint 17 Qiana.
While Ubuntu provides an upgrade path, so everything should run smoothly.
Upgrade from Ubuntu 13.10 to Ubuntu 14.04:
If you are using Ubuntu 13.10, you can easily upgrade to Ubuntu 14.04. All you have to do is install the update-manager-core package:
$ sudo apt-get install update-manager-core
And run the upgrade process and follow the GUI instructions:
$ sudo do-release-upgrade
Upgrade from Linux Mint 16 to Linux Mint 17:
Linux Mint does provide an official way to upgrade, so the best thing to do (if you don’t want to perform a fresh install) is to replace the repositories with the qiana/trusty ones and upgrade all the packages of the system, as I have written here:
Change the repositories from saucy to trusty and from petra to qiana, in the /etc/apt/sources.list file:
$ sudo sed 's/saucy/trusty/' /etc/apt/sources.list
$ sudo sed 's/petra/qiana/' /etc/apt/sources.list
Change the repositories from saucy to trusty and from petra to qiana, in the /etc/sources.list.d/official-package-repositories.list file:
$ sudo sed 's/saucy/trusty/' /etc/apt/sources.list.d/official-package-repositories.list
$ sudo sed 's/petra/qiana/' /etc/apt/sources.list.d/official-package-repositories.list
Change the repositories from saucy to trusty and from petra to qiana, in the /etc/sources.list.d/official-source-repositories.list file:
$ sudo sed 's/saucy/trusty/' /etc/apt/sources.list.d/official-source-repositories.list
$ sudo sed 's/petra/qiana/' /etc/apt/sources.list.d/official-source-repositories.list
Perform the system upgrade:
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get upgrade
After the upgrade process finishes (and it may take a couple of hours), upgrade the system:
$ sudo reboot
