""" The need of this entire if conditional has to be changed
                this function is the ensure function that is called
                in the main section.
                This conditional tends to disable/enable repo for
                install present latest action, same actually
                can be done for remove and absent action
                As solution I would advice to cal
                try: self.yum_base.repos.disableRepo(disablerepo)
                and
                try: self.yum_base.repos.enableRepo(enablerepo)
                right before any yum_cmd is actually called regardless
                of yum action.
                Please note that enable/disablerepo options are general
                options, this means that we can call those with any action
                option.  https://linux.die.net/man/8/yum
