For, what to me is, an interesting data point, I would suggest doing the following now that you have a local known good copy:
On a machine that was still faulting:
for i in /var/cache/yum/base/ \
/PATHTOLOCALREPO/5.7/os/<arch>/repodata/ \
/var/cache/yum/updates/ \
/PATHTOLOCALREPO/5.7/updates/<arch>/repodata/
do
ls -l $i
md5sum $i/*
done
#you may want to unroll the for, into four terminals, for your own sanity.
#you'll have two sqlite files in each /var/cache dirs you can ignore
My bet... some isp between you and the internet is transparent proxying*** to reduce their downloading bandwidth, and they keep cache too long, the error will clear just as soon as their cache clears or you force it by wgeting the broken file with the --no-cache flag. [got the tee-shirt]
But now that you have a local mirror, the updates should go faster in the future. :)
*** I know you keep indicating no proxy is _known_ to you in the path to the mirrors, but it is pretty much the only thing that makes any sense.
