Как получить пакет showduplicates rpm, используя модуль python yum?

#!/usr/bin/env python

import sys
import yum

yb = yum.YumBase()
yb.conf.showduplicates = True
yb.setCacheDir()
yb.repos.disableRepo('*')
yb.repos.enableRepo('grafana')

plist = yb.doPackageLists(patterns=sys.argv[1:])

if plist.available:
    print "Available Packages"
    for pkg in sorted(plist.available):
        print pkg, pkg.repo
