@AUTH-IT-Center I added another update but the error you’re seeing is a little strange because it should’ve bene addressed, I don’t know. The min() item is saying it requires a value and the approach I took was to check if there is data in the array, pass it to the min funciton otherwise set it to null (which should work if true)

Of course i don’t have much time to dig deep into this today, but my testing seemed to work without much issue.

Let me see if I can create a host without an image associated, tie a snapin and make a snapin task.

@The-Dealman Awesome thank you! and we did publish 1754 specifically due to this issue (manually running the automated processes just in case your org is worried at all 🙂 )

@Tom-Elliott Sorry for the lack of clarity in my explanations and the use of screenshots unrelated to my problem.

I have upgrade to the last beta and deploy on registered host works well.
Thank you.

I’ll check if not registered host now appear in Pending Hosts.

I had some problems with AMD computers and found this

https://knowledge.broadcom.com/external/article/269598/firmware-settings-for-ipxe-boot-on-lenov.html

"Resolution
During iPXE troubleshooting it has been determined that the following settings in Firmware/BIOS for Lenovo Thinkpad L15 Gen 3 need to be adjusted to allow for a successful iPXE boot:

Memory protection - Set to ‘disabled’
AMD V™ Technology - Set to ‘disabled’

There also may be certain environments that require further changes. For further information contact Lenovo Support.

Additional DS (Deployment Solution) and GSS (Ghost Solution Suite) files can be found in KB article Updated 64-bit ipxe.efi (ipxe v1.21.1+) binaries

NOTE: The files in the above KB article are not a pointfix but are new version binaries signed by Microsoft"

Leaving it here, because it solved my problem and it sounds like your problem

@alexamore90 I think you’re asking for something like this? https://forums.fogproject.org/topic/9463/fog-postinit-scripts-before-the-magic-begins?_=1768874256297

@alperi The bit if detail you are missing is what the kernel parameters were that was sent to the fog client. From what you posted it appears that the FOG server has all of the bits in the right spots.

In the kernel parameters that are passed to bzImage during boot up it lists where the FOS engine can find the deployment server. I would verify the IP addresses are correct. If everything appears correct with the parameters, we can debug this a bit more by debug deploy and then manually interact with the fos engine from the target PC’s console.

@Tom-Elliott Alrighty. So my FOG server at another location is acting up in the same fashion with the failure to check in.

Before we used it I updated to 1.60-beta.2265 to hopefully negate it but I did not drop the fog table from mysql before doing so.

Are there any logs you want me to pull?

Was not sure which ubuntu version of these (20.04, 22.04, or 24.04) was used as the basis for the FOG release v1.5.10.1734.

Thanks, @FOGBreaker101, for the version you are using.

Some software doesn’t use the latest released version of the OS distro, but often one major version back.

@CanadienITGuy Just for your and anyone’s fyi the autoexec.ipxe... Not Found is not an error. It’s more of an info message than a warning or error.
I actually have tested adding an autoexec.ipxe, even just an empty file to remove that message but even an empty file or a file that is even just a symlink or copy/paste of our normal ipxe/boot menu files causes things to break in the process.
The autoexec.ipxe is meant for adding customization to the ipxe process without needing to re-build the ipxe binary. But my testing with it within the fog workflow was that it’s best to just let that message exist and to see it as it being not found means the process will not be altered from your expected Fog ipxe workflow

@george1421 Thank you for this suggestion. This disabling of “fastboot” worked PERFECTLY! I interrupted the OOBE with Shift + F10 and got the command line window. I shutdown using the “shutdown.exe -s -t 0” command you suggested. Then after booting up, the FOG capture task I had already started took over and it captured 100% as it should have.

Essentially, I had forgotten to disable fastboot like I normally do on EVERY computer I have. So when it “rebooted” it technically wasn’t rebooting the device since fastboot is a misguided absurd hibernation feature Microsoft developed. The error I got was nearly identical to the one in the original post.

Thanks so much for this suggestion George and all!

@siarkowski I believe I have found the cause of this.
A while back, right after the version you reverted too, we added an improved queueing system which is working perfectly in 1.6. However when we ported it backwards into 1.5.10.x I made a simple syntax error (the wrong $task->id vs $task->get('id') ). I have fixed this in the latest dev-branch.

This should also greatly improve the experience of the imaging task queue (see also https://github.com/FOGProject/fogproject/issues/736 and https://github.com/FOGProject/fogproject/issues/691) I thought I also wrote a post somewhere in the forum walking through the updated process that fixed some longstanding date math issues, but I can’t find that now.

Point being, if you would be so kind as to update to the latest dev-branch version and see if it fixes the issue, that would be very helpful.

@eliaspereira This should be fully fixed in the stable release of 1.5.10.x coming on the 15th of this month and in the dev-branch as of now.
I thought it was already fixed back in September, and it has been working in 1.6 since then but we just got a report of a related issue here https://forums.fogproject.org/topic/18081 which I believe I just fixed.

@tian @DBailey635 @eliaspereira Apologies for missing this post. This was fixed in August-ish of last year, see also:
https://github.com/FOGProject/fogproject/issues/736

I found this searching for a post I wrote about it, as I’m pushing another fix for this for a bug just found in 1.5.10.x

If you update to the latest dev-branch (or what will be stable on the 15th of this month) or give the working-1.6 branch aka 1.6-beta a try, you’ll find the queuing problems fixed.

@Tom-Elliott

Great news!

I updated my server to Debian Bookworm, restarted the Fog installation, and the accent problem disappeared. Awesome!

Thanks for your help and happy new year 2026, all the best for the FOG project!

@Tom-Elliott Thank you, Tom. The init version is now 2025xxx. I’ll test soon to confirm the SSD info is showing in logs.

@brent could you specify exactly at which point of the installation you see this error? If you notice the installer hangs or fails specifically during the “pinning” stage, it is likely a name resolution issue.

I’ve found a solution for this: you need to manually edit the Windows hosts file at C:\Windows\System32\drivers\etc\hosts and add an entry with your FOG server’s IP address followed by the name “fogserver”. This ensures the SmartInstaller.exe recognizes the server and can download the certificate properly.

Just adding my case here in case it helps someone else with the same error.

I’m running FOG 1.5.10 on RHEL 9.5. In my case the problem was not iPXE, kernels or init.xz, but a broken NFS setup on the FOG server.

When I tried to rerun installfog.sh, it always failed at “Starting NFS server” with a systemd dependency error. Checking systemctl list-dependencies --failed nfs-server.service showed that one dependency was a failed mount coming from /etc/fstab. It was an old ISO mount pointing to a path that no longer existed.

Because that mount failed, nfs-server could not start, and FOS Linux failed to mount its root filesystem over NFS, causing the kernel panic on UEFI clients.

After removing the invalid mount from /etc/fstab, running systemctl daemon-reload, fixing NFS exports and starting nfs-server, I was able to complete installfog.sh and UEFI PXE boot started working again.

@bond007fink @jayrehme
By “Latest Update” do you mean the December updates for Win 11 or do you mean the latest release version of 25H2 ? I haven’t tested 25H2 yet.

@pbriec Sorry that your post got lost in the shuffle, I saw it pop up with @raul’s response.
I imagine/hope you got past this in the last year but just in case, the fix would most likely be resetting the host encryption from the web ui (removes some token related database entries on the host record) then restarting the fog service on the client.

If that didn’t do the trick, then restarting the fog service along with resetting the hots encryption should fix it.

@nicolas-moraes I managed to solve it and in my case it was not a FOG or network issue. I verified that DHCP was working correctly (confirmed with tcpdump), options 66/67 were unchanged, TFTP was running, and the FOG web/ipxe boot.php were reachable.

The key test was that when the client stayed at “Start PXE over IPv4”, the FOG server was not receiving any DHCP or TFTP requests at all, which pointed to a client-side problem. Even though Secure Boot and Fast Boot were already disabled, the issue was caused by the BIOS state.

After restoring BIOS defaults on the HP laptop and re-enabling PXE IPv4 boot, everything started working again. It seems some UEFI/PXE flags were stuck, and resetting the BIOS fixed it.
