First, there were problems with corrupt header.info files. Now there are problems with various headers (first libebml-devel, now libmatroska-devel).
I've gone so far as to do a yum clean all, and try again, but the same results are had..
I've now gone even a step further and renamed /var/cache/yum, recreated the directory and started a new yum check-update. It downloads a bunch of headers, but pukes and dies on the same packages as before.
Any thoughts? I've emailed Dag, but with no response.
