Tried to upgrade from 10.10 to 11.04. Got the following error message midway. Pretty sure some packages did download, because the second and third times I tried, it skipped the download-for-several-minutes-before-the-error-message stage.
Could not download the upgrades
The upgrade has aborted. Please check your Internet connection or installation media and try again. All files downloaded so far are kept.

I checked a few of them; they seemed to be just a digit or two off from packages that are in the relevant directories. Is my system requesting versions that aren't out yet for some reason?
