This question already has an answer here:

I have ubuntu 12.04 on my computer. I found a command line that would update my software, but it did not work. When I entered:

sudo do-release-upgrade

into terminal, it asked me for my password, it checked for an update, and said No new release found. This deeply frustrates me because I know there is an update. Please help before I smash my laptop to tiny bits.

This isn't an answer, just a comment, but the only available release upgrade for Ubuntu 12.04 is Ubuntu 12.10 which is only supported by updates until January, 2014. If you wait another 6 months to upgrade, you will be able to upgrade instead to Ubuntu 14.04 which will be supported by updates until April, 2019. Ubuntu 14.04, like Ubuntu 12.04, will be a Long Term Support release. –  karel Oct 13 '13 at 23:03
The reason is that your system is configured to upgrade only to a new LTS version of Ubuntu, the upcoming 14.04. To change that setting, see askubuntu.com/a/336588/88802 –  gertvdijk Oct 13 '13 at 23:06

You must run the following command:

sudo do-release-upgrade -d

If you want either by GUI:

sudo update-manager -d

Computers have feelings, too!! (Well, computers that run Linux do.)

  1. Go to "Software and Updates"
  2. Go to the Updates tab
  3. Click the dropdown menu next to "Notify me of a new Ubuntu version"
  4. Select "For any new version" and try the command again.

Keep in mind that you will have to upgrade to Ubuntu 12.10 and then upgrade to 13.04 from there.
