Same problem here while trying to yum install some packages, using various mirrors .. I was lucky enough to find one with valid (old?) data to proceed with installing, but it seems there's been some distribution of bad meta data
I did try the yum clean all, and that didn't fix anything, seems to be a mirror data problem
<snip> [Errno -1] Header is not complete.
Does anybody else see the same problem ?
Yes, I've seen these error messages. Try running "yum clean all" - that's what fixed it for me...
