Fix Package Versioning Issues on Linux
On Red Hat, `dnf` helps you install packages and then continues to aid in the management of these packages after their install. One of the key features of `dnf` (and `yum` before it) is that it tracks not just the package itself, but also how the package relates to its dependencies — and the things that depend on this. `dnf versionlock` gives you even greater control of the package/dependency relationship, letting you lock packages to specific versions, preventing updates. In this lab, you’ll explore how versionlocking works in relation to your `ruby` package. _This lab is not approved or sponsored by Red Hat._
