As you observe below I have provided the exact version and architecture of the rpm with yum command so that yum will not consider any other rpm to perform the downgrade. So let us try to install old rpm version of bash to ' 4.2.46-28.el7'. Now let us downgrade bash rpm using yum # yum downgrade /tmp/bash-4.2.86_64.rpmĮxamining /tmp/bash-4.2.86_64.rpm: bash-4.2.86_64

Yum localinstall
