You could try "yum clean all; yum update --disablerepo=*hand*" just to see if you can get any sort of updates. If not, it sounds like your repository files have been modified in some way. Check your repository files, each repository should have a line similar to this: mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os If this line is present, but different (Excluding the repo= part), for example pointing at a non-centos domain and location it would mean that they have been modified which is causing these errors you are receiving. Hope this helps :-). Kind Regards, Jake Shipton (JakeMS) GPG Key: 0xE3C31D8F GPG Fingerprint: 7515 CC63 19BD 06F9 400A DE8A 1D0B A5CF E3C3 1D8F
