needs code inspection if that still applies. I kinda recall that software-properties uses qapt-batch to update though, so this is probably fairly necessary. whether discover should depend on software-properties is another question to which I guess the answer is no.

software-properties

softwareproperties/kde/SoftwarePropertiesKDE.py:                cmd = ["/usr/bin/qapt-batch", "--update"]

discover

libdiscover/backends/PackageKitBackend/PackageKitSourcesBackend.cpp:    auto service = PackageKitBackend::locateService(QStringLiteral("software-properties-kde.desktop"));

:(

so, iff s-p is installed it is listed as a startable service in the settings' burger menu to give access to more advanced options. meaning we could opt to not ship it by default as it is not necessary. OTOH maybe the way to go is to do something with s-p where we check for qapt-batch OR pkcon to do the cache update. then again the two aren't equal as the point behind qapt-batch is that it gives a gui whereas pkcon doesn't and python-apt doesn't either unlesss a custom one is written which was decidedly avoided here.

So, after a look I'd say discover needs s-p to actually edit sources. packagekit doesn't allow editing, only enable/disable and deleting sources, so s-p is necessary to actually manage the sources.lists as such I think we are probably better off keeping it.

now what we could do is add a simple flag to software-properties to use pkcon instead of qapt and then rip out qapt from the default ISO.

so discover calls s-p --pkcon or somesuch and it would then run pkcon refresh on exit. meaning we keep everything working but can avoid qapt on the ISO. this would be rather fidly though, I'll have to think about it a bit

I don't have this installed. Needs checked if it got sorted or if we stopped installing s-p-k even though we still need it
