Introduction

Managing installed software is just as important as installing it. This lesson will teach you how to remove, update, and manage software packages using the apt package manager.

Learning Objectives

  • Remove software packages using apt remove and apt purge.
  • Update installed software using apt upgrade.
  • Clean up unnecessary packages with apt autoremove.

Removing Software

If you no longer need a software package, you can remove it using apt remove. For example:

    sudo apt remove git

To remove a package and its configuration files, use apt purge:

    sudo apt purge git

Updating Installed Software

To update all installed packages to their latest versions, use:

    sudo apt upgrade

For a more thorough upgrade that handles dependencies better, use:

    sudo apt full-upgrade

Cleaning Up Unnecessary Packages

Over time, unused packages can accumulate on your system. To remove packages that are no longer needed, use:

    sudo apt autoremove

Summary

In this lesson, you learned how to manage installed software by removing, updating, and cleaning up packages using apt. Keeping your system clean and up-to-date is essential for maintaining performance and security.
