What the Uninstaller Does

Upon confirmation, the script performs the following actions to clean the system:

1. Stops and Disables the Service: It stops the active wg-quick@wg0 service and disables it to prevent it from starting on the next boot.

2. Removes Packages: It uses the system's native package manager (apt, yum, dnf, pacman, apk) to remove the wireguard-tools and qrencode packages.

3. Deletes Configuration Directory: It completely removes the /etc/wireguard directory, which contains the server configuration, keys, and the params file. This action is irreversible.

4. Removes Sysctl Configuration: It deletes the /etc/sysctl.d/wg.conf file to disable IP forwarding on the next reboot.

5. Reloads System Configuration: It runs sysctl --system to apply the removal of the IP forwarding rule immediately.

After these steps are completed, WireGuard will be fully removed from your system.
