For some days now muon doesn't finish with the usual grey finish window and the "all up to date" message. It just shows an empty package list control. I'm sorry, but I'm still not very experienced in trouble shooting on Linux/Kubuntu. But I tried to get some error messages by running it from Terminal. Maybe this might help: ****** $ muon-updater QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave. Object::connect: No such signal org::freedesktop::UPower::DeviceAdded(QDBusObjectPath) Object::connect: No such signal org::freedesktop::UPower::DeviceRemoved(QDBusObjectPath) $ JSonScanner::yylex - error reading from io device Bus::open: Can not get ibus-daemon's address. IBusInputContext::createInputContext: no connection to ibus-daemon JSonScanner::yylex - error reading from io device found error while replying QDBusError("org.freedesktop.DBus.Error.InvalidArgs", "") ****** I'm still running Kubuntu 14 LTS and yes I know I should upgrade, but I need to run some programs that seem to cause problems on newer Ubuntus, so at the moment this is not an option for me. Maybe someone could help me nevertheless. Thank you :) Jens
This muon updater issue has been solved today. It looks as if the cause was a hanging update of "libreoffice-l10n-de" which now has been solved today and this as a consequence seems to have solved the muon updater issue. So sorry for maybe causing unnecessary library entries and thank you anyway.
