This is because you are using the PackageKit session interface, which needs a session service (like GNOME Software) to provide the frontend bits. Ideally, KDE Discover would support that too, but it doesn't. See https://www.freedesktop.org/software/PackageKit/pk-faq.html#session-system for more information on this. Apper does provide the session interface, but Apper isn't developed anymore, it only receives some maintenance fixes - I *might* reintroduce it for Stretch though, because I got a lot of requests to please add the package back. The problem is that last time I tested it, Apper didn't work so well, so when I introduce it to unstable again and see that it isn't actually fit for release inclusion, I would drop it in time for the Stretch release again. So, tl;dr: Don't count on Apper being available in Stretch. Another solution is of course to use the PackageKit system interface via the GIR and provide the necessary GUI dialogs by yourself. In any case, this is not a bug in PK but expected behavior which can only be solved by something in the user session providing the PK session interface. Cheers, Matthias -- I welcome VSRE emails.
