Updating headers in ubunta

“Restart Now…” should open the usual confirmation alert.

If “Automatically check for updates” is checked, Ubuntu should become due to check for updates at the specified interval after updates were last checked.Once it is due to check for updates, it should try to check one minute after the first time any administrator connects to the Internet (bug 323108, bug 414202).By default, it should not display any interface while checking.Our presentation of software updates should carefully balance promptness against interruption, and automation against informed consent, to maximize the prompt installation of updates across the millions of devices on which Ubuntu is installed.The “Notify me of a new Ubuntu version:” menu should contain options “For any new version” (the default for a non-LTS, replacing “Normal releases”), “For long-term support versions” (the default for an LTS, replacing “Long term support releases only”), and “Never”, in that order.
