The error message indicates the QPA plugin is either missing, or cannot be loaded. Please check if
/usr/lib/*/qt5/plugins/platforms/libqpa-mirserver.so exists. If not, qtmir-desktop is the source of that file. If it is there, could you do initctl set-env --global QT_DEBUG_PLUGINS=1 and try launch unity8. The ~/.cache/upstart/unity8.log file will contain the useful output. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1485609 Title: unity8 desktop crashed with SIGABRT in qt_message_fatal() Status in unity8 package in Ubuntu: New Bug description: This occurs with the last round of updates when trying to start a desktop session.
