I know I've seen this documented somewhere before, but what's the option to keep update-manager from prompting for updates except for LTS-to-LTS releases?

If you go to Ubuntu > System > Administration > Update Manager, you'll see a Settings... button at the bottom left of the dialog. In the dialog, switch to the Updates tab and uncheck the updates checkboxes and set Release Upgrade to "Long Term Support Releases Only".

It should look something like:

See the community docs for more information.

    The given picture is misleading: "Release upgrade" is set to "Normal Releases", where it should be "LTS Releases" – MestreLion May 26 '11 at 23:06

    Is there a way to do this without the GUI? I have an Ubuntu VPS that keeps pestering me to upgrade to 12.10. – dgw Jan 03 '13 at 04:28

    @dgw You'll probably want to check out /etc/update-manager/release-upgrades. You can set Prompt to lts instead of normal and that should help. Run 'do-release-upgrade' to check if it finds a new release. – flickerfly Oct 24 '13 at 18:24

Posting as an answer what @flickerfly said in a comment: the way to do it without a GUI is to change the value of Prompt in /etc/update-manager/release-upgrades.

[DEFAULT]
Prompt=lts

The possible values are (copied from the file itself):

  • 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.
