=== Why This Is a Nightmare for Software Maintenance === Dependencies can become a serious problem over time: # '''Conflicting Requirements:''' If program A needs <code>libshit</code> version 1.2 & program B needs <code>libshit</code> version 2.0, your system can break when one application upgrades. # '''Complex Upgrades:''' Updating dependencies for one application can & will cause another application to stop working. This is called '''dependency breakage''' and they are another common cause of chasing rabbits all the way to hell. # '''System Decay:''' Over time, manually managing dependencies can lead to a bloated, unstable system full of broken packages, outdated libraries, & leftover files. # '''Version pinning misery:''' <code>apt</code> lets you install specific versions of packages but managing version conflicts becomes timewasting, dangerous, & difficult when dependencies span dozens of packages with intricate relationships. As a newbie, you are likely going to break your system. As an experienced sysadmin… they still broke their systems…. <span id="how-docker-solves-this-mess"></span>
