After searching on Google, I got the following suggestion for an error 
message.:

Please help me move up from kde 4.2.2 to 4.2.3.  I have been trying on my own 
for days without success.  Additionally please notice the Error message above.  
'Error: “/var/tmp/kdecache-steven” is owned by uid 1000 instead of uid 0.  
What does that mean?  User ID 1000 as opposed to User ID 0?

Does the error need correcting, if so, how?  Thanks!

Steven
