How to fix duplicate rpm issue during SA upgrade process

Issue

When there is rpm duplicates error like below while doing upgrade, it is either ctrl-C was hit while upgrading or there is connection problem(system crashed or reboot) therefore leaving the upgrade incomplete.
New packages might be installed, but old packages are not removed.

yum-utils-1.1.30-30.el6.noarch is a duplicate with yum-utils-1.1.30-17.el6_5.noarch
nspr-4.9.5-2.el6_4.x86_64 is a duplicate with nspr-4.9.2-1.el6.x86_64
nss-3.14.3-4.el6_4.x86_64 is a duplicate with nss-3.14.0.0-12.el6.x86_64
