#The revised script appears well-organized and more concise. It performs the following steps:

#1. Determines the package manager and system type (DreamOS or OpenSource).
#2. Removes unnecessary files and folders.
#3. Checks for mounted storage and creates a backup directory if it doesn't exist.
#4. Sets up the update URL for AJPanel.
#5. Downloads and installs various panels and scripts, including icons and commands.
#6. Configures the `ajpanel_menu.xml` and `ajpanel_settings`.
#7. Updates Enigma2 settings and restarts the Enigma2 service.

#Here's the final version of the script:
#```sh

#!/bin/sh
#
echo " download and install panel emil nabil "

# Determine the package manager and system type
