Comment 1 for bug 224486

Thanks for reporting this bug. This sounds like a problem with a file on the servers. This type of problem often resolves itself after the server gets updated. The best solution is often to try again later or in another day or two. If this problem persists for a few days let us know and please attach the files from /var/log/dist-upgrade for the failed upgrade. Please also let us know if you are able to upgrade successfully so that we can close this report
