Problem: nothing provides kf5bluezqt-bluez4 needed by droid-config-device-bluez4-1-1.armv7hl
 Solution 1: Following actions will be done:
  deinstallation of bluez-configs-mer-4.101+git73-1.31.1.armv7hl
  deinstallation of bluez-4.101+git73-1.31.1.armv7hl
  deinstallation of connman-1.30+git20-1.31.1.armv7hl
  deinstallation of connman-configs-mer-1.30+git20-1.31.1.armv7hl
  deinstallation of connman-qt5-1.0.98-1.32.1.armv7hl
  deinstallation of ssu-network-proxy-plugin-0.42.0-1.35.2.armv7hl
  deinstallation of ssu-0.42.0-1.35.2.armv7hl
  deinstallation of sdk-register-0.5-10.1.11.jolla.armv7hl
  deinstallation of qt5-qtsysteminfo-5.2.0+git8-1.7.1.armv7hl
  deinstallation of qt5-qtdeclarative-systeminfo-5.2.0+git8-1.7.1.armv7hl
  deinstallation of ssu-vendor-data-jolla-0.95-10.32.2.jolla.noarch
 Solution 2: keep obsolete bluez-configs-mer-4.101+git73-1.31.1.armv7hl
 Solution 3: break droid-config-device-bluez4-1-1.armv7hl by ignoring some of its dependencies
