"Bad Header line"

[senectus]

For the past few weeks I've been getting this every time I do an "update"

http://archive.ubuntu.com/ubuntu/dists/hoary-updates/Release.gpg: Bad header line
http://archive.ubuntu.com/ubuntu/dists/hoary/main/binary-i386/Packages.gz: Bad header line
http://archive.ubuntu.com/ubuntu/dists/hoary/restricted/binary-i386/Packages.gz: Bad header line


Any idea's on what's going on?
