For most of the summer, the main Debian Apt repository I use has had a hash mismatch with a couple of their files which tends to stop apt-get upgrade in its tracks.
Failed to fetch http://debian.yorku.ca/debian/pool/m...p17-3_i386.deb Hash Sum mismatch
Failed to fetch http://debian.yorku.ca/debian/pool/m...enny2_i386.deb Hash Sum mismatch
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
Is there a formal route to notify the repository of this? The issue is rectified when using another repository so the issue is repository specific and not maintainer specific.
