Description of problem: ModemManager conflicts with some use cases, as it (just one example) steals ttyUSB devices during boot and plug in. There is no way to disable MM. Recommended solution is to uninstall it when its services are not needed. This was fixed in NetworkManager itself https://bugzilla.redhat.com/show_bug.cgi?id=873402#c5 , but KDE plasma applet pulls it in and prevents uninstallation. The dependency chain should be broken somewhere and it should be possible to uninstall ModemManager witthout uninstalling this plasma applet too. The best solution would probably be for MM part to go to extra subpackage as is true for kde-plasma-nm-{vpnc,openvpn,pptp,...} Version-Release number of selected component (if applicable): kde-plasma-nm-0.9.3.2-3.fc20.x86_64 How reproducible: always Steps to Reproduce: yum remove ModemManager Actual results: kde-plasma-nm removed Expected results: kde-plasma-nm stays
We already tried to remove ModemManager as dependency, but I don't know how to do that, because kde-plasma-nm requires ModemManager only for -mobile subpackage, but the problem is that libmm-qt requires ModemManager and libmm-qt is required by libnm-qt which is required by kde-plasma-nm. So the chain is kde-plasma-nm → libnm-qt → libmm-qt → ModemManager.
We decided to remove ModemManager as dependency in libmm-qt, I'll do it together with packaging of a new version, which should be very soon.
