Hi, i have resolved this problem by reinstall the modemmanager. yum reinstall ModemManager.x86_64 systemctl restart ModemManager systemctl enalbe ModemManager Regards Andreas
Can confirm this issue after upgrade with fedup from f19 to f20. Also resolved this by reinstalling ModemManager.
This is a problem for me as well. I can work around by problem by either starting MM manually or by renaming "/usr/share/dbus-1/system-services/org.freedesktop.ModemManager1.service" to something else.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates.

If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
