As predicted, it was the spanning tree protocol on the Cisco switch.

I verified it worked just fine with a dumb switch connected through the Cisco switch. And it worked just fine.

So I just turned off Spanning Tree on the switch, since it’s a standalone switch.

Thanks for your help!

Thanks, will try a dumb switch and report back. And I can always adjust (or turn off) the spamming tree stuff on the switch, as it’s usually not connected to other switches.

The reason I think just a second or two longer delay would work is that I literally watched the light on the switch interface it is orange while negotiating and doing its thing, then green when it’s fully connected. The green happens literally a second after the third attempt

The initial PXE boot from the laptop works just fine, BTW.

I’m having an issue with some computers where my switch doesn’t finish negotiating speed/duplex, doing spanning-tree, etc, before the udhcpc process tries three times.

Watching it in person, it looks like the interface on the switch comes up literally a second after the 3rd attempt to get a lease. Here’s a photo of the error I’m getting:

My question is: can I have this process try 4 or 5 times instead of 3 times? Is this a setting or piece of code I can alter somewhere?

Replying to myself in case anyone else has the same issue.

error log has this:

../lib/common/functions.sh: line 535: ntpdate: command not found
Generating locales (this might take a while)...

On a bare, minimal install Ubuntu 18.04 server, you need to install software-properties-common and ntpdate.

So…

apt install -y software-properties-common ntpdate

seems to fix those errors.

Hi guys,

Installing a brand new FOG server on a Ubuntu 18.04 server, from scratch.

I have nothing on the server other than Ubuntu, open-vm-tools, and git.

I downloaded the Fog installer with git, and went through the installation process. I get this result:

 * Here are the settings FOG will use:
 * Base Linux: Debian
 * Detected Linux Distribution: Ubuntu
 * Server IP Address: 192.168.7.21
 * Server Subnet Mask: 255.255.255.0
 * Interface: ens160
 * Installation Type: Normal Server
 * Internationalization: 0
 * Image Storage Location: /images
 * Using FOG DHCP: No
 * DHCP will NOT be setup but you must setup your
 | current DHCP server to use FOG for PXE services.

 * On a Linux DHCP server you must set: next-server and filename

 * On a Windows DHCP server you must set options 066 and 067

 * Option 066/next-server is the IP of the FOG Server: (e.g. 192.168.7.21)
 * Option 067/filename is the bootfile: (e.g. undionly.kpxe)


 * Are you sure you wish to continue (Y/N) y

 * Installation Started

 * Installing required packages, if this fails
 | make sure you have an active internet connection.

 * Adding needed repository....................................Failed!

Can anyone point me in the right direction to figure out what is causing this?

Thanks in advance.
