You may want to report this to the apt mailinglist, though with a bit more information (apt version, etc...) But to me the error indicates that the repodata file either is empty or not properly XML. Is it possible that the location of the repository simply is wrong, or that you have permission problems on those files so that they fail to be downloaded ? Reporting this to the apt mailinglist may make apt provide a cleaner error message, but if the cause is not within apt you will have to fix the cause anyhow.
