Why is Gnome updates collecting KDE packages?

[Hedley]

I recently bought a new laptop and immediately wiped out Windows and installed Ubuntu Koala 64 bit version. I've noticed on the most recent list of updates that Update manager is recommending, under a category labelled 'Backports', that I update a bunch of apparently KDE-related packages, though I use Gnome.

The packages are:

kde-icons-oxygen
kdebase-runtime
kdebase-runtime-bin-kde4
kdebase-runtime-data
kdebase-runtime-data-common
kdelibs-bin
kdelibs5
kdelibs5-data
khelpcenter4
libplasma3

What's with this? Am I using KDE and don't even know it (this seems unlikely)? Are these actually not KDE-specific, despite the naming? If these should not be inthe update list, how are they getting there? And how do I get rid of them? I don't see anything in my repositories list that might be requesting them.

Thanks,

HB

You may have some applications that are KDE and rely on some KDE runtime data and stuff...also themes. Nothing to be alarmed about.

Fair enough. I just wanted to make sure something wasn't misconfigured and installing unnecessary stuff.

Thanks!
