@piaFOG26 There is nothing on fog that says “you must update” though most likely we’d have recommended it.

Ubuntu 20 LTS went EOL June 2026. That aside, we need more informaiton please.

Provide the install logs and maybe a screenshot of the actual error you’re seeing when trying to update.

Also, worthwhile, might be worth installing the 1.6.0-RC version (RC-14 is the current latest available) as likely by mid November, it will become the latest official available release.

Either way, please provide more information.

Thank you,

@Tom-Elliott

Thank you!

As you thought, it was a double DHCP server… Even though .6 was in bridge mode, the DHCP server on it was still enabled, unlike the other MikroTik switches we have. Disabling it brought the iPXE booting back. I’ve run a re-inventory task and am now running an image capture task.

I’ll have to keep a future eye open for that as we expand our classroom network.

Cheers!

@robertkwild So you’re good now?

@robertkwild The issue most likely is not coming from the flip of Secureboot On/Off.

Unsigned or test-signed boot drivers. This is where a real BSOD can happen. If the machine has bcdedit /set testsigning on or nointegritychecks, and a boot-start driver depends on that (an unsigned storage or RAID driver, some sketchy anti-cheat, a dev build), turning Secure Boot on makes those settings get ignored. If the storage driver doesn’t load, you get INACCESSIBLE_BOOT_DEVICE. That one only happens in the off-to-on direction.

@Paladin1 Thanks, that explains the registration error. Registration reads the machine’s disk, so it needs a disk attached. With no disk it stops with that message every time. That is expected, so you do not need the debug task.

For your question: neither. Do not reinstall anything yet.

The BIOS boot mode on this machine applies to both the network boot and the installed OS. Your image is a UEFI install, so this machine has to network boot in UEFI too. We can try a different iPXE file for UEFI that loads its own network driver. That can avoid the firmware error.

On the FOG server:

Edit /etc/kea/kea-dhcp4.conf. In the classes FOG-UEFI-64-1, FOG-UEFI-64-2, FOG-UEFI-64-3 and FOG-Surface-Pro-4, change "boot-file-name": "snponly.efi" to "boot-file-name": "ipxe.efi". Run sudo systemctl restart kea-dhcp4-server. Set the target BIOS back to UEFI and network boot it.

Tell us if you get the FOG menu or the same ASSERT. If it fails, change the file back. A re-run of the installer also puts snponly.efi back.

@Tom-Elliott said in Login to delete image not passing correct username.:

@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?

I attempted to migrate to the 1.6…my server looks like it just migrated from 1.5 to the same 1.5 version, but it does look like it cleared up whatever issue it was having. Feel free to close this ticket.

Thanks

@Tom-Elliott
thanks it was lighttpd so i purged it

@Paladin1 Thanks for the report. You’re right, the docs were out of date.

The installer now asks Install/update the FOG database schema now? (Y/n) and does the schema update itself when you answer yes, which is the default. The browser step only applies if you answer no.

The “Denied” you saw is expected on a new install. With no FOG users yet, the schema page only accepts the link the installer prints, which ends in &fogtoken=.... On an existing install, you log in as an admin instead.

The install pages are updated for both versions:

1.5: https://docs.fogproject.org/en/latest/1.5/installation/server/install-fog-server/ 1.6: https://docs.fogproject.org/en/latest/1.6/installation/server/install-fog-server/

@fierke A correction to my last post. The fix is now merged into working-1.6 and rc-1.6.0. Update your checkout and re-run the installer. The installer now writes default.ipxe without those two lines, so you do not need to comment them out again.

You are right that this can happen on other machines too. Any UEFI firmware that never ends its variable list hangs the same way. The update fixes it for all of them.

I would still like the show efi/SecureBoot result and your BIOS version when you have time. That confirms the cause before the iPXE side ships.

@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.

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