I am grasping at straws here... Very, very unlikely... but check the SHA512SUM of your file: befb34516673a4f31a89cd1ef2e7e4ae2a57a7c2130f956bf4734c2ab253f86503417037d720f0fbc18844004b79e2da2a7668042951ba46cee24b9562d20c28 ../../../6/main/x86_64/repodata/3e2ca432eee448392bed25e4ace4fc5cc5bd7c9c03ba52235a6350e3c0fe6d3d-primary.sqlite.bz2 (Should be cached somewhere in /var/cache/yum.) I have two possible thoughts: your firewall is doing weird stuff, like unpacking .bz2 files, checking them for viruses and re-packing them. That could either corrupt the file or, more likely make signature checks fail. Second one: your HTTP cacher cached an incomplete/corrupt file. Mihai
