The 403s are in fact weird, but they are explainable. The reason for them is that the 'Sources', and 'Packages' files do not exist in uncompressed form on S3 *or* on the *.archive.ubuntu.com mirrors (see http://us.archive.ubuntu.com/ubuntu/dists/natty-updates/universe/source/ )
The reason you see the 403 is that apt got bad data for the Sources.bz2 (or Sources.gz) and decided to try the 'Sources' as a fallback. It does unfortunately hide the real issue quite well :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/932088 Title: Ubuntu EC2 package mirror intermitent failures To manage notifications about this bug go to: https://bugs.launchpad.net/linaro-android-infrastructure/+bug/932088/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
