I think if you open update manager there should be an update option on there.

Click the button that says "Settings." Then go to the Updates tab and look at the drop down menu for the panel called: Notify me of a new Ubuntu version. There are three settinsg. Any new version; for long tem support versions & never. You need the setting: for long term support versions.

Software and Updates> Updates tab> set 'notify me of LTS releases' at the bottom option> close. That will update and show you there is a new LTS release available. Accept.

Before doing the upgrade disable any PPAs you have installed manually from third-parties.

Alternatively if you where to want to change the setting manually, you can edit the file:
/etc/update-manager/release-upgrades
and change the line that has prompt= from whatever it says, to prompt=lts.

Be aware that which ever method to change the settings you choose you need to do either a check(in the update manager)
or run apt-get update (from the command line)
So that the updated settings can take affect.
12.04's update manager might ignore the change at first and not do an automatic reload/update.

Sidenote: since you are running this as root, no need for sudo.

Also, funny thing is do-release-upgrade command actually doesn't require sudo to work.
(It'll ask for your password eventually, but will start and run initially without it.)


Just a couple of thoughts, anyway...
