    Do you want to run YUM install checks ?  [y/n]
    This will increase your upgrade duration time wise.
    Check the change log
    to see if any Nginx or PHP related new additions
    which require checking YUM prequisites are met.
    If no new additions made, you can skip the
    YUM install check to speed up upgrade time.
