📝 Provide a clear and concise description of the issue.

Better check for /etc/apt/apt.conf.d/no-nag-script existence before trying to delete it, otherwise post install script will interrupt. I modified original script like this:

...
  no)
    whiptail --backtitle "Proxmox VE Helper Scripts" --msgbox --title "Support Subscriptions" "Supporting the software's development team is essential. Check their official website's Support Subscriptions for pricing. Without their dedicated work, we wouldn't have this exceptional software." 10 58
    msg_error "Selected no to Disabling subscription nag"
    if [ -f /etc/apt/apt.conf.d/no-nag-script ]; then
      rm /etc/apt/apt.conf.d/no-nag-script 2>/dev/null
    fi    
    ;;
  esac
  apt --reinstall install proxmox-widget-toolkit &>/dev/null || msg_error "Widget toolkit reinstall failed"
...

Original script interrupts when both conditions occurring:

• selected 'no' to disable subscription nag
• no 'DPkg::Post-Invoke' script exists on the system

🔄 Steps to reproduce the issue.

1. run PVE Post Install script on a fresh system
2. select 'no' at the "Disable subscription nag" question

❌ Paste the full error output (if available).

script fails silently
