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?

  • Just to be sure, you are using Ubuntu Server? Just to know whether you need a GUI or CLI answer.

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

    I figured there was a l33t/config file way of doing this, didn't know it though! Glad you posted this answer, will definitely remember this for the future. Jun 23, 2015 at 15:39

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:

enter image description here

That's it! Now you can now upgrade via the Software Updater GUI or via do-release-upgrade!
