I just had a computer built, and I didn’t think to check compatibility beforehand, but it’s got a RealTek LAN card, which doesn’t work out of the box with Proxmox. I’ve tried the graphical installer, the terminal installer, and both of them with debug on. Each time, it says it can’t detect network interface. I read a tutorial, but I think it’s for an older version of Proxmox, that says to download the driver from another system and put it on a USB drive. I’ve done that, but I can’t get either GUI or terminal installer, with or without debug to mount the second drive so I can install the driver. What do?
