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.

Why, then, is do-release-upgrade (without the -d) still saying "No new release found" a few days after the .1 has been released in iso form? (My /etc/update-manager/release-upgrades says "Prompt=lts") –  tudor Aug 1 at 1:00

From an inspection of the code, it seems that "normal" releases default to a URL changelogs.ubuntu.com/meta-release which lists 14.04, and LTS releases use the URL changelogs.ubuntu.com/meta-release-lts which doesn't list it at all. I think they haven't updated the meta information yet. –  tudor Aug 1 at 1:28

That seems like a release oversight, can you file a bug and CC me? email is in my profile, thanks! –  Jorge Castro Aug 1 at 3:20

@JorgeCastro Is this indeed a release oversight, and is there any idea when it will be fixe? Was a bug filed, and where can I follow it? (I searched, but could not find it. I also want to switch from 12.04 LTS to 14.04.1 LTS, and I just want to do it through the Update Manager.) –  Marnix Klooster Aug 9 at 7:12

Looks like changelogs.ubuntu.com/meta-release-lts is fixed now. –  DLosc Aug 11 at 20:52
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 ?

Will try this, thanks. :) I feel stupid for not realising that. –  CullenDM Apr 28 '12 at 2:16

10.04 releases won't upgrade right away, see the link I posted above. –  Jorge Castro Apr 28 '12 at 2:18
    
Thanks for the info! :) –  CullenDM Apr 28 '12 at 3:47

I was trying to update a 12.04 to 12.10 and also got stuck by the no new release found issue. If one has no access to a GUI and wants the update on terminal, one has to edit

/etc/update-manager/release-upgrades

to match:

[DEFAULT]
# Default prompting behavior, valid options:
#
#  never  - Never check for a new release.
#  normal - Check to see if a new release is available.  If more than one new
#           release is found, the release upgrader will attempt to upgrade to
#           the release that immediately succeeds the currently-running
#           release.
#  lts    - Check to see if a new LTS release is available.  The upgrader
#           will attempt to upgrade to the first LTS release available after
#           the currently-running one.  Note that this option should not be
#           used if the currently-running release is not itself an LTS
#           release, since in that case the upgrader won't be able to
#           determine if a newer release is available.
Prompt=normal

To test that the correct version is found, one can run do-release-upgrade -c.

If that shows correct version, run:

sudo do-release-upgrade -d

I had a similar issue. I simply changed from Prompt=normal to Prompt=lts and it worked just fine for me. –  Florin Coada Sep 9 at 10:48
