The issue is due to duplicate rpm in server

cPanel has a auto script to fix this issue

You need to use command /scripts/autorepair fix_duplicate_cpanel_rpms to remove duplicate rpm in server

root@server1 [/usr/local/apache]# /scripts/autorepair fix_duplicate_cpanel_rpms

This fixed the issue for me and now upcp is working fine.
