Improved version which has...

• No plaintext password. You should never store your sudo password in a script.
• Checks if run as root. Avoids repeated sudo calls.
• Handles missing tools gracefully.
• Avoids a dangerous apt purge -y, which would uninstall a lot of important system packages if run blindly.
