How to disallow Ubuntu to upgrade from like 11.10 to 12.04?

I know that its your wish if you want to upgrade, but I don't want the message in update manager that says a new release is available to get displayed.

    Open the /etc/update-manager/release-upgrades with your favorite text editor, ie:

    sudo nano /etc/update-manager/release-upgrades

    enter image description here

    Change the Prompt= line from Prompt=foo_setting to Prompt=never.

    If you want a graphical way of doing it open the Ubuntu Software Center and under Edit > Software Sources > Updates you will find a Notify me of a new Ubuntu version option, from the drop box select Never.

  2. Or just use sed! We just added this to our setup script to avoid our users from borking their own systems by doing upgrades.

    sudo sed -i 's/Prompt=.*/Prompt=never/' /etc/update-manager/release-upgrades

  3. To stop Ubuntu nagging you:

    nano /etc/update-manager/release-upgrades

    Change Prompt=normal to Prompt=never:

    To exit nano press the combination CTRL + X and then answer to the question of saving changes with Y.

  4. You can also just disable checking altogether by doing:

    apt-get remove ubuntu-release-upgrader-core

  5. On newer versions of Ubuntu, using the GUI, you should see an option

    Notify me of a new Ubuntu version, therein select Never
