Proxmox Post Installation Script

Overview

This script automates post-install configuration on a Proxmox VE system. It performs the following tasks:

  • Configures NTP (using chrony) based on your detected country
  • Disables the Proxmox subscription nag message
  • Adjusts repository settings (disables Enterprise, enables Community)
  • Installs and configures LLDP for Linux-style interface name reporting
  • Downloads and installs the latest Intel Microcode update (v3.20241112.1)
  • Upgrades server packages
  • Provides interactive management for High Availability (HA) services
  • Optionally installs a pretty login banner with system information
  • Prompts for a system reboot at the end

Dependencies

  • Root privileges are required
  • The following utilities must be available:
    • curl
    • sed
    • wget
    • apt-get
    • dpkg
    • systemctl
    • dmidecode (for pretty login banner)
  • An active network connection is necessary during execution

Usage

  1. Save the script as "post-install.sh"

    chmod +x post-install.sh
  3. Run the script as root: 
    sudo ./post-install.sh
  4. Follow the interactive prompts to select your desired configuration options

Key Features
