libmuon/backends/ApplicationBackend/ApplicationNotifier.cpp checks for updates to Kubuntu and pops up a notification but that can disappear and leave no trace. It would be good if the notification was in the systray slideout plasmoid too same as package updates are. Reproducible: Always Steps to Reproduce: 1. put "212.13.202.11 changelogs.ubuntu.com" into /etc/hosts 2. check it works by running muon-updater and seeing the update bar at the top 3. run apt update, see notification of Kubuntu update but nothing in systray plasmoid
