1. Install a Package
To install a package, use the apt install command:
sudo apt update # Update the package list

3. Purge a Package
To remove a package along with its configuration files, use the apt purge command:
sudo apt purge {package} # Replace {package} with the package name
4. Clean Up Unused Dependencies
After removing or purging packages, there may be unused dependencies that can be cleaned up using the apt autoremove command:
sudo apt autoremove
5. Clean Up Package Cache
To clean up the local repository of retrieved package files and free up disk space, use the apt clean command:
sudo apt clean
6. Verify Package Installation
To check if a package is installed and view its version, use the following:
{package} –version # Replace {package} with the package name
Summary of Commands:
Install: sudo apt update && sudo apt install {package}
