# ==========================================================
# Description:
# This script safely updates your Proxmox VE system and underlying Debian packages
# through an interactive and automated process.
#
# Main features:
# - Repairs and optimizes APT repositories (Proxmox & Debian)
# - Removes duplicate or conflicting sources
# - Switches to the recommended 'no-subscription' Proxmox repository
# - Updates all Proxmox and Debian system packages
# - Installs essential packages if missing (e.g., zfsutils, chrony)
# - Checks for LVM and storage issues and repairs headers if needed
# - Removes conflicting time sync packages automatically
# - Performs a system cleanup after updating (autoremove, autoclean)
# - Provides a summary and prompts for reboot if necessary
#
# The goal of this script is to simplify and secure the update process for Proxmox,
# reduce manual intervention, and prevent common repository and package errors.
