I have tried absolutely everything, without good results...
yum always fails with "sqlite.bz2 File does not match checksum" for different repositories, every single time, but always with the above error.
ive tried setting ... * http_proxy * http_caching * disabling fastestmirror * changing settings in sysctl.conf
all with the same result,
Im starting to think it might be a bug?...related to http://bugs.centos.org/view.php?id=5116
