[kubuntu] Kubuntu Will Not Update

I've been playing Guild Wars for a few weeks, so it's been awhile since I last logged into Kubuntu Linux. So, I decided to log in to run the update utility, to get the lates security patches and whatnot, but I ran into problems. How do I fix this? (To be clear, I clicked on the "Check for updates" button in the first screenshot, and got the error message in the next screen shot. The third screenshot is just me scrolling down.)

Here are the screenshots:
