I am running OBS 1.6 and trying to import the latest RHEL6 beta releases (which should be similar to the Fedora 13 release) and have run into the problem below. The 'preinstall' stage appears to complete successfully. The first RPM that build attempts to install, in this case ca-certificates, hits this error: done installing ca-certificates-2009-2.el6 error: unpacking of archive failed on file /etc/pki/java/cacerts;4c0d1fa4: cpio: Digest mismatch I've tried changing the order of install, whatever RPM is installed first always hits this problem, so it isnt a problem with the ca-certificates RPM.
