I think we're in the clear on this piece now. I was able to package distro- release-notifier from Harald Sitter et al (https://invent.kde.org/system/ distro-release-notifier) which uses the existing backend of Ubuntu's update- notifier. This means that it doesn't have to use appstream and launches the proper do-release-upgrade GUI frontend. I have tested it in 20.04 and it works properly, so I intend to get this into Ubuntu Studio (and discuss it further with Kubuntu so they don't end up in this situation again). -- Erich Eickmeyer Project Leader - Ubuntu Studio Member - Ubuntu Community Council
