How you can help This specification includes many small changes and enhancements to the current update behavior, but they can be implemented in any order. Grab the code ( or ) and submit your own branch.

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. Idea: Make this more predictable by letting you specify which day of the week it opens. Whenever an update is downloaded and ready to install, or a background update download has failed repeatedly, or “Download future updates automatically” is set to “Never” and an update is available for download: • Wherever the System Settings icon appears, it should have a badge with the number of updates available (bug ). • On the System Settings main screen, “Updates” should have the same badge (bug ). • Inside System Settings, the should have an “Updates available” or “Update problem” item, with the number of updates available as the summary value.
