I'm following the upgrade instructions on Ubuntu's website, but on launching the upgrade tool I get this response:

Checking for a new ubuntu release
No new release found

Am I doing something wrong? Is there a workaround?

Here's my /etc/lsb-release:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.4 LTS"

According to Ubuntu Engineering Foundations team manager Steve Langasek:

Upgrades between LTS releases are not enabled by default until the first point release, 14.04.1, scheduled for July. It is recommended that most LTS users wait until then before upgrading to 14.04.

If you choose to upgrade before then, you can pass the -d option to the upgrade tool, running do-release-upgrade -d or update-manager -d, to upgrade from vanilla 12.04 to 14.04. (-d stand for devel)

This question explains the justification for waiting for the prompt.

sudo do-release-upgrade -d 

Notice the -d at the end.

2 options :

  1. Burn the iso and put it in your drive, it will detect the upgrade automatically

  2. Go in you synaptics options, then Preference > distribution > Always prefer the highest version.

Problem solved ?

10.04 releases won't upgrade right away, see the link I posted above. –  Jorge Castro Apr 28 '12 at 2:18
