I'm having no luck authenicating for package updates. I'm always meet with "Incorrect password, please try again", but I can sudo and run apitude just fine with the same username/password, So I then looked at /var/log/messages and see messages each time I tried the update of:

I’m seeing the same problem.
One interesting thing to look at is /var/log/auth.log:
