Greetings,
I am currently working on a Bash script to automate the Proxmox VE installation on an offline Debian 12 setup. The goal is to enable a Proxmox installation on air-gapped systems.
My goal is to enable an offline installation while having GUI access on the server itself without using an additional machine to access the GUI.
I downloaded all the packages referred to in the Proxmox documentation explaining the installation of Proxmox over Debian 12 Bookworm, and everything is running smoothly. The issue I have is when I need to access the GUI. The bridge interface I use cannot get UP and stays DOWN despite having it set to "auto" in my /etc/network/interfaces.
Also on the first run I get an error with network restarting process. Note that it is run on a freshly installed Debian and no network connection as been made when the script is executed.
On a virtual machine, the system works thanks to the isolated network triggering the interface, but on a Debian installed on bare-metal, it does not work.
Any ideas?
For the bare-metal install, I had to set up the IP address manually and used the same address I use in my script for my bridge. Sometime I got an error message for services failing to start while they are installed.
I’ve included the code below.
If anybody has an idea about what the issue might be, please let me know. Otherwise if you guys have an existing method to get the job done I am all ears
