I have been struggling to get anyting installed.

When running Install software I get the following message

Code:
PackageKit is blocking software management.
This happens when the updater aaplet ir another software management application is running

Ask Package kit to quit?


YES/NO
If you choose yes the same message appears again and aigain and again, ie PackageKit never stops

When you choose no

Code:
Accesing the SOftware management failed

System management is locked by the application with pid 2474 (or whatever) (/usr/lib/packagekitd). 
Close this application before trying again
Would you like to abort or try again?
Trying again gets you nowhere
If you try to stop the pid with top in a Terminal it says that it is an invalid id

I have via System ==> Configuration ==> Software management

got to Apper


I clicked on the wrench and chose
Code:
Check for distribution upgrades NEVER
Check for updtes NEVER
I have rebooted but still get the same issue!

What do I do now?

Thanks in advance!
