OK, I now understand what is going on. Software updates are divided into two groups, security updates and others. Security updates are implemented as they arise, taking account of your preferences in "Software Updates". The others are queued up and executed once a week, regardless of your settings. If you opt for "automatically install", you get no indication that the update is under way, security or not. Thank you, Michael, for pointing to that thread: http://lists.fedoraproject.org/pipermail/test/2011-May/100453.html I agree that the Software Updates GUI is unsatisfactory; it isn't clear what effect the settings have. -- James Bridge <james@xxxxxxxxxxxxxxxx> -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
