I was just going to enter this in the bugs database, but creation of new accounts is apparently broken. (When I try to set the initial password after following the link in the confirmation email, "This account is protected. You are not allowed to access this until the account protection is lifted.") I have an x86_64 system, on which I must install the gtk+.i386 package. To begin with, only the x86_64 package is installed: # cat /etc/rpm/macros.query_format %_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch} # rpm -q gtk+ gtk+-1.2.10-33.centos4.x86_64 When I try to install the i386 version, I get this error: With yum: # yum -y install gtk+.i386 [...] Transaction Check Error: package gtk+-1.2.10-33.centos4 (which is newer than gtk+-1.2.10-33) is already installed With straight rpm -i: # rpm -i http://mirror.stanford.edu/yum/pub/centos/4.4/os/x86_64/CentOS/RPMS/gtk+-1.2.10-33.i386.rpm package gtk+-1.2.10-33.centos4 (which is newer than gtk+-1.2.10-33) is already installed This problem only exists with the CentOS gtk+.x86_64 package, the RedHat one is fine. rpm -i --force works, and that is the workaround I'm using.
