Hi guys just a quick heads up. 

The package pk-updates became available for translation in kf5-trunk 
playground-base (three different POs/POTs) a few days ago.

It's a PackageKit based updater, which is used by default on Fedora and 
openSUSE - so it's a quite visible package. And of course it is also an option 
for any other distro with a packagekit-backend.

Translating it was very quick because I had almost all the strings in my 
Lokalize translation memory anyway (I'm guessing from Apper or Muon).
