How to Uninstall SaltStack on Ubuntu

SaltStack, often referred to simply as Salt, is a powerful configuration management and orchestration tool. While it offers a range of features to automate the setup and maintenance of infrastructure, there may be instances where you need to uninstall it from your system.
