[SOLVED] Proxmox 8 - Network failure right after installation

Hello everyone,

I have some interesting times lately. We had no problems with Proxmox 7 and everything was working and so we wanted to try new version 8. Installation went ok, both network ports were working during installation and data were flowing, but right after the restart after successful installation both ports went dark, no blinking, no data. And to be extra cringe, Promox is happily saying "yo, this is ip address, just connect to it dude".. well I would if any network interface were working.

I believe there is a BUG in the installation procedure, where names of network interfaces are mangled somehow. Check the pictures in attachment.

Jesus, I don't understand it.
I restarted couple of times, got back to installation (not installed), rebooted, and now its apparently working? How that could happened, why? Nothing was changed.

Ok, it seems to be working now, but I am really scared that after another couple of restarts it will stop work again.
