Troubleshoot Library Dependency Issues on Linux

Applications, services, and other software often have to perform some overlapping functions to be able to function. These functions are often collected into libraries and then used dynamically across software after being loaded into memory. In this lab, we'll practice how to look up which of these dependencies are in use and how to fix things when one is missing or corrupted. _This lab is not approved or sponsored by Red Hat._
