We started with an Ubuntu 11.10 for a server system. The upgrade to 12.04 went smoothly. Now I only want to upgrade to the next LTS release. However, the system keeps telling me that 12.10 is available. Although this is true, I want to stick to LTS from now on.

How do I switch the release-"mode"?

I want the system to act like I installed it from an LTS-image.

UPDATE

After logging into the system I am greeted by

Welcome to Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-63-generic x86_64)

 * Documentation:  https://help.ubuntu.com/
New release '12.10' available.
Run 'do-release-upgrade' to upgrade to it.

The file /etc/update-manager/release-upgrades has Prompt=lts configured.

    If its a server, you have not installed ubuntu-desktop and you don't have a GUI, right? – jobin Jun 06 '14 at 15:32

  • @mikewhatever: The answer might be the same, but the questions is different in sense, so it can't be a duplicate of that. – jobin Jun 06 '14 at 15:46
  • @jobin Why waste keystrokes? Got a better answer? Post it! – mikewhatever Jun 06 '14 at 15:50
  • @Jobin correct, there is no X installed. – kronn Jun 06 '14 at 16:01
  • @mikewhatever I'm gonna try the answer you linked to. As I am looking for this a long time already, I don't consider this a duplicate (in question). I'll see about the answer. – kronn Jun 06 '14 at 16:03
  • Why don't you try booting from the Ubuntu Server 14.04 installation disc (or flash drive) and let the installer do it? – John Scott Jun 06 '14 at 16:23
  • It's our main database server, @FuzzyToothpaste, so rebooting just to get rid of one line of text only I see is a little over the top ;-) . It's not blocker, but something I really want to understand. – kronn Jun 06 '14 at 16:32

OK, I was reading another answer, and it had this:

Upgrades between LTS releases are not enabled by default until the first point release, 12.04.1/14.04.1, scheduled for July/August. It is recommended that most LTS users wait until then before upgrading to 12.04/14.04.

Ubuntu 14.04.1 is scheduled for July 24th.

Hope that explains why you don't get the 14.04 prompt.

PS: As you guys don't seem to like my duplicate suggestions, I humbly concede, and post this as a possible answer.

    I'll wait until the release of 14.04.1 and see what happens then. I am a little confused why it's offering me the upgrade to 12.10, though… – kronn Jun 06 '14 at 20:28
  • After the release of 12.04.5, I get a hint to update to 14.04.1. Thanks for the explanation. – kronn Aug 25 '14 at 06:41
