Update Errors

I booted up my computer (which still takes an average of 5 minutes) and was alerted that there were now 5 updates available. I hit the status icon and it pulled up the update manager. I told it to check for updates and it reported an error. It could not download all repository indexes. It said I had 5 updates for 2.1 MB. I told it to apply the updates and it reported another error that it could not fetch the updates. When I clicked okay, it checked for updates again and did not report an error so I told it to apply the updates again. It applied them without an error and reported that there were no additional updates available.
