I'm using Ubuntu 11.04. The update manager once found the new release 'oneiric', and still shows up this screen when I log on use ssh:

Welcome to Ubuntu 11.04 (GNU/Linux 2.6.38-14-generic x86_64)

 * Documentation:  https://help.ubuntu.com/

0 packages can be updated.
0 updates are security updates.

New release 'oneiric' available.
Run 'do-release-upgrade' to upgrade to it.

Last login: Wed Apr 25 16:22:48 2012 from ***

But I didn't upgrade then, and change my apt sources. And now I cannot upgrade to 'oneiric'. do-relase-upgrade shows:

$ sudo do-release-upgrade
Checking for a new ubuntu release
No new release found
$

And apt-get dist-upgrade shows:

$ sudo apt-get dist-upgrade
Reading package lists... Done

I can successfully update all my packages.

What may be the problem of this?

  • @fossfreedom I tried with no success. I've already had update-manager-core installed, and prompt=normal. I can update the successfully, but only dis-upgrade cannot find the next version.

Check /etc/update-manager/release-upgrades

Prompt=lts

will cause upgrade to fail if the release you are currently on is not an LTS one.

Solution:

Change Prompt=lts to Prompt=normal and save the changes

Do the required upgrades until you have installed a LTS release.

Then change back to Prompt=lts

Done.

  • I already have this set to prompt=normal. I'm sorry I only mentioned this in one of the comments to the question.

To upgrade from Ubuntu 11.10 or Ubuntu 10.04 LTS on a server or system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.

    I'm not using 10.04 LTS but 11.04. But anyway, sudo do-release-update -d seems to do the work. The machine is now getting oneiric packages.

    This worked OK here, but you should not use -d when attempting to upgrade to another stable release. -d will upgrade to a development release if one is available to upgrade to from the current release, which would be quite undesirable in a production environment. Just leave off the -d flag for normal upgrading. Commented Jun 30, 2012 at 5:43

    Note that when /etc/update-manager/release-upgrades contains Prompt=lts, sudo do-release-update -d can be used to upgrade to a stable, non-lts, release. I'm currently at precise, have configured to only upgrade to the next lts , but sudo do-release-update -d will upgrade to quantal (which has long been stable at the time of writing)

One possible reason is that the release available stamp file hangs around incorrectly. The following fixes this issue:

sudo rm /var/lib/ubuntu-release-upgrader/release-upgrade-available

This file is safe to remove as it will be regenerated next time the motd script runs if appropriate.


Reason: this issue came up for me in 13.04 after a partially completed release upgrade which I completed with apt-get distupgrade. If the stamp file in /var/lib/ubuntu-release-upgrader/release-upgrade-available exists and has a message that a new release is available, it is shown on every login via the motd script: /etc/update-motd.d/91-release-upgrade, which calls /usr/lib/ubuntu-release-upgrader/release-upgrade-motd to update the stamp if it's empty. See these files for more info on why this hangs around.

  • This is what worked for me, running do-release-upgrade -d tried to update to 13.10 dev release Commented Jun 11, 2013 at 2:59

    In 12.04 the stale update file is in /var/lib/update-notifier/ (not ubuntu-release-upgrader/), but everything else still applies.

This can also happen if apt is configured to use a proxy and the proxy does not work properly. In my case the file /etc/apt/apt.conf.d/01proxy contained the line

Acquire::http::Proxy "http://proxy.local:9999";

and the server proxy.local was not responding. Removing this line fixed the "No new release found" issue with the graphical and terminal update tool.

In my case, a running 12.04 will not offer to upgrade to 12.10. The reason is because there are compatibility issues with my video hardware in 12.10. The tools told me after I tried to force the upgrade.

I had the problem with 12.04 - > 13.04 and it was fixed by using -d option as guided coleman/Kagan above i.e.:

do-release-upgrade -d

For old releases that have reached their EOL cycle, you can try this:

Download the meta-release info locally with this instruction: https://askubuntu.com/a/502485/34298

It's possible to happen if you are using do-release-upgrade under socks client (proxychains or tsocks command). Your socks server or socks client does not support DNS lookup. Workaround for this is adding host entries to /etc/hosts file while distribution upgrade:

91.189.88.17    old-releases.ubuntu.com
91.189.92.201   archive.ubuntu.com
91.189.91.15    security.ubuntu.com
91.189.95.36    changelogs.ubuntu.com
