Bug 789788

I can not get yum-updatesd from package yum-updatesd-0.9-8.fc16.noarch to function properly in daemon mode or in oneshot mode. NetworkManager is connected and functioning. Network availability seems to never be correctly detected.

Using the following command line with oneshot and debug options 
"/usr/bin/python -tt /usr/sbin/yum-updatesd -o -d" gives the result:
**********
Going to exec: ['/usr/libexec/yum-updatesd-helper', '--check', '--network-fail', '--download', '--deps', '--apply', '--dbus', '--email', '--email-from=yum-updatesd', '--email-to=root', '--smtp-server=localhost:25', '--sendmail', '--syslog', '--syslog-level=WARN', '--syslog-facility=DAEMON', '--syslog-ident=yum-updatesd', '--debug']
Check for updates failed: No network available

The command "dbus-monitor --system" shows:
