Disable Ubuntu Update Manager's new version warning

Question

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.

All help will be appreciated

Answer 1

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

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

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.

Answer 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

Answer 3

You can also just disable checking altogether by doing:

apt-get remove ubuntu-release-upgrader-core

Answer 4

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.

Answer 5

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

Notify me of a new Ubuntu version, therein select Never
