[CristianD]

Hello,
I got a problem and i dont understand why not even me not even my colegue.

We whanted to install Debian 9.12 on 1u Server R410 and we get Red screen with the network error, same think on 6 other servers, we tested even on manualy configuration with static ip even dhcp, same, same same.

We ar able to install any other OS only on Debian 9.12 the network is not working at all, even if we skip/move forword the configuration and make it manualy, still the same but te massive think is we got lots of Proxmox servers witch they ar with debian and we never ever had any problems at all, only and only on Debian

TEsted wit cd iso, netinstall ...etc same same same

Dose any one know what we ar doing wrong ? or we ar so idiots we ar unable to install an OS ?

Thank you

I don't know what you are doing wrong. Anyone else ?
The other question, well I prefer not to answer, but the way you write speaks for itself.
Have you tried reading some of the Debian documentation on networking ?

Your box came with almost a dozen different network interfaces. Care to tell us which one?
