do-release-upgrade will work but not until 14.04.1 is available in July.

From the Ubuntu mailing list "Users of 12.04 LTS will be
offered the automatic upgrade when 14.04.1 LTS is released, which is
scheduled for July 24th."

If you really want to upgrade now, supply -d (development version) option.
sudo do-release-upgrade -d

    When I enter `sudo do-release-upgrade -d` at a command prompt I get a "command not found" error. Am I supposed to do something else prior to this?

    Do you have the ubuntu-release-upgrader-core package installed?
