I installed Centos3.4-x86_64 and I notice that I get duplicate packages. i.e. I also notice that the duplate packages exist on the cd install as well. [root at bayamo RPMS]# rpm -qa | grep pam_krb pam_krb5-1.73-1 pam_krb5-1.73-1 when I use apt after downloading from Dag's site it complains about duplicate packages after running apt-get update. I am missing something to get my x86_64 system to update with apt the same way i386 system does, Mebbe someone can provide a hint.
