  • Because Ubuntu 12.04 is a Long Term Support release (meaning that it is supported with bug fixes and security updates for 5 years) you won’t find a pop-up telling you that a new version is available.

    If you want to upgrade,you can follow these instructions

    1. Open Update Manager from either the Power Menu or the Dash.
    2. Click the ‘Settings’ button in the lower-left corner of the Update Manager window: This will open Software Sources.
    3. Click the menu next to “Notify me of a new Ubuntu version” and select ‘For Any New Version’

    enter image description here

    1. Important DO NOT uncheck or alter anything other than the above.

    Once you’ve made the change you will likely be prompted to input your user password. After this, close Software Sources, then close and then reopen Update Manager.

    . Click the ‘Upgrade’ button to begin your upgrade to Ubuntu 12.10.
