Hello Guys,

thanks for all these information,

I installed FOG 1.2 (old) and updated later to the 1.4 on the same server with debian 9 .

I had the same problem
<
The server will boot to the FOG menu, but after selecting the quick registration, the system does not get an IP address

It have simply an wrong ip adresse in FOG configuration, like :

TFTP Server

Web Server

(wrong ip from the old install, ip adress changed)

after fixing the fog server ip address every things works fine.

Debian9 fully compatible with FOG1.4

Bye

Hassan
