If you want to upgrade from Ubuntu14.04/13.10/13.04/12.10/12.04 or older to 14.10, just follow the steps given below. Note that you cannot upgrade directly from 13.10 to 14.10. You should upgrade from 13.10 to 14.04 before upgrading from 14.04 to 14.10. Here are the detailed steps.

The following steps can be used not only for 14.10, but also for some Ubuntu derivatives such as Lubuntu14.10,Kubuntu14.10 and Xubuntu14.10

Important: before upgrading, just to be on the safe side, don't forget to save your data on a flash drive or external hard drive.

Server upgrade

To upgrade from a ubuntu14.04 server to a 14.10 server, follow these steps.

Install the update-manager-core package if you haven't installed it before:

Sudo apt-get install update-manager-core

Edit the file / etc/update-manager/release-upgrades.

Sudo nano / etc/update-manager/release-upgrades

Set up Prompt=normal or Prompt=lts as follows

# Default behavior for the release upgrader. [DEFAULT] # Default prompting behavior, valid options:## never-Never check for a new release.# normal-Check to see if a new release is available If more than one new# release is found, the release upgrader will attempt to upgrade to# the release that immediately succeeds the currently-running# release.# lts-Check to see if a new LTS release is available. The upgrader# will attempt to upgrade to the first LTS release available after# the currently-running one. Note that this option should not be# used if the currently-running release is not itself an LTS# release, since in that case the upgrader won't be able to# determine if a newer release is available.Prompt=normal

You can now update your service system with the following command.

Sudo do-release-upgrade-d

Now remember that the system is already version 14.10. Once again, if it is not a security problem that must be upgraded to solve, it is best not to upgrade, but to use various external means to solve it.
