Hi There, Install Centos 4.1 X86-64 onto an athlon64 box. unfortunately half way through a yum -y upgrade I press ctrl-c on the wrong window and aborted a couple of the packages in the (large) update. Now the rpm database things there are multiple packages installed on the same rpm versions, eg: >rpm -q -a | grep mysql mod_auth_mysql-2.6.1-2.2 php-mysql-4.3.9-3.6 mysqlclient10-3.23.58-4.RHEL4.1 mysqlclient10-3.23.58-4.RHEL4.1 mysql-devel-4.1.10a-2.RHEL4.1 mysql-4.1.10a-2.RHEL4.1 mysql-4.1.10a-2.RHEL4.1 libdbi-dbd-mysql-0.6.5-10.RHEL4.1 rpm -e mysqlclient10-3.23.58-4.RHEL4.1 error: "mysqlclient10-3.23.58-4.RHEL4.1" specifies multiple packages So I tried a "yum clean all" and tried again but yum fails with a transaction check error with conflicts of rpms onthemselves. I did a rpm --rebuilddb with no joy, and i deleted the __db files from /var/lib/rpm - still no joy. I cn't install any rpms now as it says there are conflicts.... I am fresh out of ideas now... Any help appreciated... P.
