I’m using Ubuntu as my operating system and when I go for update of 12.04 LTS from the available options for updating, I get an error message like the given one in the screenshot. Can you please help me?

The action would require the installation of packages from not authenticated sources.

Software update problem in Ubuntu
This error can be solved in the following ways:
1) Change the download Server to a different one. This can be done by clicking on settings in the Update Manager and choosing "Download from:" from the "Ubuntu Software" tab. You can then say "other" and select the server of your choice. Once finished, authenticate, click "close", then click "Check".
After selecting a server you will still get an error unless you click the "Check" button on the "Update Manager" window. Also since many mirror servers will be listed on the "Choose a Download Server" window you can click the "Select Best Server" button to have Ubuntu determine the best mirror server.
2) Type this command in the terminal.
sudo apt-get update && sudo apt-get upgrade or edit Update Manager settings (try this first if you already configured Update Manager).
Launch Update Manager and try again installing the update.
