Hi! On a SL system installed with only x86_64 packages i try to install a emi middleware component which have also i686 dependencies .. the problem is that i see this: [root@grid04 yum.repos.d]# yum --disablerepo=xrootd* install db4.i686 ...snip... Error: Multilib version problems found. This often means that the root ...snip... Protected multilib versions: db4-4.7.25-17.el6.i686 != db4-4.7.25-18.el6_4.x86_64 the problem is that i cannot uninstall the x86_64 as all the system will be uninstalled ... Any idea about this? Thanks! Adrian
