If the partial check, and any previous check, found no installable updates, this should be followed simply by “Settings…”, “Check Again”, and “OK” buttons.But if the partial check, and any previous check, If the check fails because of an error, the progress window should morph into an error alert, with the title “Software Updater” and primary text depending on the exact situation (bug 1153569, part of bug 1026060).
By default, it should not display any interface while checking.
When checking interactively, Software Updater should display only a progress window.
As with any other progress window, the window should have a minimize button but no maximize or close button, and should be 33 em wide.
If you stop the check, the progress window should morph into an info alert with the title “Software Updater” and primary text “You stopped the check for updates.”.
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.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).) updates has been implemented in Ubuntu Software Center, those particular updates should no longer cause the alert listing updates to appear.They should still be shown in the alert when it appears for any other reason, but they should not be checked (and should therefore not be installed) by default.check for updates finds that they are uninstallable, the progress window should morph to an error alert with “Settings…” and “OK” buttons.
