@jmeyer This is a bug in schema step 284 on MySQL. Your data did not cause it.

Cause: on MySQL, an ALTER TABLE re-checks the default of every column. Your hosts.hostSecTime still has the old default 0000-00-00 00:00:00. MySQL’s default sql_mode (NO_ZERO_DATE) refuses that default, so the step stops. MariaDB servers do not show the problem.

Fix: https://github.com/FOGProject/fogproject/pull/1838 is merged into dev-branch. While the steps run, the schema updater now relaxes the zero-date check for its own session.

The fix reaches the stable release on October 11. To continue now, install from dev-branch:

cd /root git clone -b dev-branch https://github.com/FOGProject/fogproject.git fogproject-dev cd fogproject-dev/bin ./installfog.sh -y

The failed step changed nothing in your database, so you do not need to restore the backup. The backup the installer made is still at /home/fogDBbackups/fog_sql_1.5.10.2482_20261009_113907.sql.

@Tom-Elliott
Hi, the new EXP_20261001-163131 work like a charm without the postinit workaround. Thank you!

@mmaus Would you mind updating to the latest RC or even the working-1.6 branch, if that’s too much a leap, what about upgrading to dev-branch? (It will become stable on Sunday if I recall the timing correctly.) See if we already fixed the problem you’re seeing?

@Tom-Elliott I wondered if that was the case, thank you.

@Tom-Elliott So I’ve copied my /opt/fog/snapins/ssl folder, and the ca-key in /etc/fog/pki/root/ca/ folders, then followed your advice above and re-ran the installer. The legacy agent still won’t communicate consistently it seems. Our existing agent seem to be communicating I think, but fresh installs of the legacy agent are having nothing but issues from what my team are telling me.

@Tom-Elliott
These are the two machines that were just cloned!

I deployed the Snap-in three times:
the two newly cloned machines and one old machine to see if any certificate issues arise with the old computers. All of them were assigned Image B.

The computer, which has not yet been cloned, did not process the snap-in.

Resetting the encryption settings, deleting the snap-in that wasn’t running, and restarting it didn’t help…

Rebooting of the pc helped

@astrugatch I don’t think it matters really. The issue was more about the initial pinning of the certificate during the install process. After it is pinned I think this is the correct expectation (it should only communicate to the FOG server over HTTPS).

@Tom-Elliott
Hi!
I have updated to the latest dev-branch version.
No more updating database … failed error.
The multicast session closing the right way.

Thank you!

This can be closed. Thank you.

Awesome and thank you. Confirmed working.

Hi Tom,

In my case the culprit was /images/postdownloadscripts/fog.postdownload.

echo "Activating boot partition..." sfdisk --activate /dev/sda 1 echo "Rebooting..." reboot -f

Fix was simply commenting out (or deleting) those lines. After cleanup the file looks like this:

cat /images/postdownloadscripts/fog.postdownload #!/bin/bash ## This file serves as a starting point to call your custom postimaging scripts. ## <SCRIPTNAME> should be changed to the script you're planning to use. ## Syntax of post download scripts are #. ${postdownpath}<SCRIPTNAME>

Thanks for the pointer, Tom — saved me from chasing GPT partition tables for a problem that had nothing to do with them.

@mp12 Thanks for the logs. This is a bug in 1.5.10.2482, not your node passwords.

A security change in 2482 removes the storage node password from the node data that the API returns. The image and snapin replicators read their node list from that same data. So they now send an empty password, and every node rejects the login. The Undefined property: stdClass::$pass warning is that missing field.

The fix is merged to dev-branch: https://github.com/FOGProject/fogproject/pull/1770

To get it now, update from dev-branch:

cd /path/to/fogproject git checkout dev-branch git pull cd bin sudo ./installfog.sh -y

Or wait for the next stable release. Your stored passwords are correct, so you do not need to change anything on the nodes.

@AUTH-IT-Center I do believe snponly would be the recommended, rather than iPXE’s driver.

The developers at iPXE wrote the driver on their own (of course using documentation and stuff, but for all intents/purposes it is still a handrolled driver) so anything is possible.

We shipped the native iPXE 2.0.0 mainly because of the feature it allows with actual Secureboot capabilities and instead of embedding everyfile with a custom script, a more dynamic approach for when iPXE releases new version we can upgrade more easily.

For what it’s worth, I would almost want more people to default to snponly.efi (or secureboot/snponly-shimx64.efi if using/wanting secureboot after enrolling your machines of course) because this is supposed to be using the generic driver for EFI boot protocols on the NIC rather then attempting to discover the NIC using a driver loaded.

@Tom-Elliott I edited the sshd_config file and changed
/usr/lib/openssh/sftp-server
to
internal-sftp

I’m not sure how the installer failed to make this accomodation in the first place but I’m glad it appears to be working. I deployed the image to another laptop to make sure everything is working. It looks like the problem can be considered resolved now. Thanks for your help!

@gmaurice resetting the host encryption in the gui and then restart the fog service and it should be back up and running. You can also use the api for this, the FogApi powerhsell module (links in my signature) I have this Reset-HostEncryption function https://fogapi.readthedocs.io/en/latest/commands/Reset-HostEncryption/?h=reset+host which will also handle this reset.

Your other other option is to look into post download scripts, there’s some examples in the forums and the docs. If you’re using sysprep and unattend.xml you can inject domain join information into the unattend.xml after imaging and before windows launches for the first time, so the computer is joined to the domain before the fog service or any ui is reachable.

@Tom-Elliott Thank you, tested, confirmed it’s fixed.

@Balage80 Thanks for confirming the enrollment fix.

UEFI boot: I think the cause is two new lines in default.ipxe. They read Secure Boot state from the firmware. iPXE reads it by stepping through every firmware variable, and some firmware never ends that list, so iPXE hangs there.

Please test this: take the new 979-byte default.ipxe and delete only these two lines. Keep everything else.

param secureboot ${efi/SecureBoot} param setupmode ${efi/SetupMode}

Does UEFI boot with that file? Please also post the make, model, and BIOS version of the machine. Note that re-running installfog.sh writes a new default.ipxe, which replaces a manual edit.

Pending MACs: these are not related to default.ipxe. They come from the legacy FOG Client’s Host Registration module. That module reports every adapter Windows sees, including Wi-Fi, Bluetooth, and virtual Wi-Fi Direct adapters. FOG stores each unknown MAC as pending, up to FOG_QUICKREG_MAX_PENDING_MACS per host (default 4). iPXE cannot see those adapters. You can delete the pending MACs. To stop new ones, add MAC fragments to FOG_QUICKREG_PENDING_MAC_FILTER (comma separated), or turn off Host Registration.

@Tom-Elliott

I can’t modify the company’s switches or other hardware since the system is in production. I’m currently rebuilding the FOG server on a VM on my PC and doing everything locally; it’ll be easier to troubleshoot that way. Gemini has wiped out all the previous messages and is giving me nonsense—I can’t seem to recreate the environment up to the capture stage anymore. Could you give me a rundown of everything that needs to be done—downloads, decompressing specific files in binary mode, etc.?

Thanks.
