In case you are interested the latest built Ubuntu 14.10 has been released and here are steps how you can upgrade your older distro to the latest release Ubuntu 14.10. Please note that you can’t directly upgrade from 13.10 to 14.04. First, you should upgrade from 13.10 to 14.04, and then upgrade from 14.04 to 14.10.
NOTICE: Before you attempt to upgrade your current Ubuntu system, please make sure you go trough backup of your important files on the system in case something goes sideways 🙂
Now, when you have your backup done on your system lets run few commands:
sudo apt-get update && sudo apt-get dist-upgrade sudo update-manager -d
First your system will get updated and then check for distro available upgrade. Once the first 2 commands finish you need to run the update-manager -d command in order to initiate the upgrade. You should get shortly a popup message that will ask you if you want to UPGRADE to Ubuntu 14.10 or click OK to stop the process.
Once you click the UPGRADE button all process gets initiated on your system and now you will need just wait till all is completed.
Once the upgrade finished on your system you will be asked to reboot your system to apply all the necessary changes to bring your system to the latest released of Ubuntu 14.10.
As you will see once you rebooted your system now the login page is already updated and letting you know that you are now on Ubuntu 14.10.
