Help with CentOS 6.8 installation

[flyhigh2017]

I am trying it install CentOS6.8 on a server using kickstart. The kickstart, kernel and initrd files are all hosted on an apache webserver. I am getting the following error during the installation :

Unable to download the kickstart file. Please modify the │
│ kickstart parameter below or press Cancel to proceed as an │
│ interactive installation.

Here's my pxe config :

kernel ${url}/CentOS6.8/repack/vmlinuz-4.9.4-1.el7.elrepo.x86_64 initrd=initrd-4.9.4-1.el7.elrepo.x86_64.img ks=${url}/ks.cfg console=tty0 console=ttyS0,9600 netroot=iscsi:@<IP>::::<TARGET_IQN>:uefi iscsi_initiator=<TARGET_IQN>:instance ip=dhcp ksdevice=link nofb
initrd ${url}/CentOS6.8/repack/initrd-4.9.4-1.el7.elrepo.x86_64.img

There are no errors in the httpd access / error logs.
I am able to do other kickstart installations off of the same file server (CentOS7, Fedora). Any idea what might have gone wrong?

Thanks!

At a guess your network connection isn't connected. You'd have to check the logs on the other screens of the installer - ctrl-alt-f2/f3/f4/f5 etc

Ctrl + Alt + F1/2/3/45 doesn't take me to the other installer screens.

These are the only options on my installer : <Tab>/<Alt-Tab> between elements | <Space> selects | <F12> next screen

I thought it was only el7 that used tmux for the other screens. Use the prompts to switch then. The second console is a root command prompt, the next ones are logs etc.

I don't think CentOS6.8 is using tmux, from what I read online it is using virtual consoles. However, Ctrl+Alt+F[2-4] key combination does nothing. I suspect the virtual consoles have not started. Could this be an X issue?

From the DHCP logs, I did see DHCP discover & ack coming from this server, so the server seems to be getting an IP, but I do not see any traffic on the network when it's trying to retrieve the ks.cfg. I suspect the network configuration is failing for some reason. I've tried static IP configuration, instead of ip=dhcp, but that did not help either. Without able to switch to virtual consoles, I'm not able to make any progress.

"<F12> next screen" that you see in the screenshot, just takes to the next screen of the installation, it is akin to selecting the defaults and pressing ok on the current screen.
