I have the version 14.04.02 (Desktop) and want to upgrade to 14.10, but when running the command:
do-release-upgrade
Me warns that has no new version available, what should I do?

That's because you're using LTS version and you're trying to upgrade to a non-LTS version of Ubuntu. Check:
cat /etc/update-manager/release-upgrades | grep -i prompt
it should print like:
# Default prompting behavior, valid options:
Prompt=lts
That means it prompted to upgrade to LTS versions but not the Development ones. If you want to upgrade to Development version of Ubuntu:
sudo nano /etc/update-manager/release-upgrades
Then substitute:
Prompt=lts
to
Prompt=normal
Then save and exit. Run:
sudo apt-get update
sudo do-release-upgrade -c -d
14.04 is a Long term support (LTS). By default it will just upgrade to the next LTS release (which will be 16.04). To upgrade to a non-LTS release, you have to open the software update properties. On the tab with the notification settings there is a drop down selection at the bottom. Set it to any release, then it should find 14.10. Also since you are using a desktop, I suggest you use the update-manager
GUI instead of the do-release-upgrade
CLI application.
This is caused by a setting that's automatically set if you install an LTS release fresh, instead of upgrading to it.
To change this, simply open up the Unity dash (Ubuntu logo in the upper-left-hand corner), and search for Software
.
That should bring up a list of applications like this (different icons of course, I'm using the Numix Circle icon theme. The text will be the same):
Select the icon titled Software & Updates.
This will open up a window that looks something like this:
Then, you'll want to click the Updates tab:
Finally, change the Notify me of a new Ubuntu version option to be For any new version:
That's it! Now you can now upgrade via the Software Updater GUI or via do-release-upgrade
