Hello everyone... I have just installed openSUSE 12.3 Gnome 3 on my laptop and I have one problem, I connected to the Internet and all that, now, I want to refresh my Repositories...
I opened Terminal and typed this command down "su" then I entered my password and then "zypper ref" and I clicked enter it said this:

"zypper ref
PackageKit is blocking zypper. This happens if you have an updater applet or other software management application using PackageKit running.
Tell PackageKit to quit? [yes/no] (no):"

I have been always getting this and it's so annoying... I shut down my computer and turn it on and same time, I left the computer for half an hour and came back to it and same thing and I restarted my computer and still the same... What should I do now? How can I turn this updater or whatever it is down?
