Updated to latest dev-branch and snapins are working now
Thansk for help.

Hello,

I have updated FOG server to the latest stable version: 1.5.10.1903.
FOG server is running on Ubuntu 24.04.4 LTS.

The problem is that now FOG clients are returning error:

Communication ERROR: Could not contact FOG server
Communication ERROR: The remote server returned an error: (500) Internal Server Error.

When I have checked apache2/error.log I have folowing error:

Wed Jul 22 09:45:28.388629 2026] [proxy_fcgi:error] [pid 676068] [client 10.0.0.107:54208] AH01071: Got error ‘PHP message: PHP Fatal error: Uncaught ValueError: min(): Argument #1 ($value) must contain at least one element in /var/www/fog/lib/fog/storagegroup.class.php:228\nStack trace:\n#0 /var/www/fog/lib/fog/storagegroup.class.php(228): min()\n#1 /var/www/fog/lib/client/snapinclient.class.php(160): StorageGroup->getMasterStorageNode()\n#2 /var/www/fog/lib/fog/fogpage.class.php(3306): SnapinClient->json()\n#3 /var/www/fog/lib/fog/fogpage.class.php(255): FOGPage->requestClientInfo()\n#4 /var/www/fog/lib/pages/dashboardpage.class.php(76): FOGPage->__construct()\n#5 /var/www/fog/lib/fog/loadglobals.class.php(65): DashboardPage->__construct()\n#6 /var/www/fog/lib/fog/loadglobals.class.php(79): LoadGlobals::_init()\n#7 /var/www/fog/commons/base.inc.php(38): LoadGlobals->__construct()\n#8 /var/www/fog/management/index.php(22): require(’…‘)\n#9 {main}\n thrown in /var/www/fog/lib/fog/storagegroup.class.php on line 228’

From the logs I assume that there is a problem with StorageGroup.
I have a few storage groups & storage nodes as per pictures below.

Snapins Storage group on this FOG server are set to GR storage.

Is my setup wrong?
Can you help me somehow?

@Richarizard504 You can try to use snponly.efi or snp.efi in your DHCP 067 Bootfile Name setting.
After change I was able to perform host registration and inventory.
Hope it helps.

@Richarizard504 There was no reply for this problem.
I think this problem started with iPXE 2.0.0+ and new Lenovo ThinkPad T16 Gen 4 (model 21QFS5BE00).

@Tom-Elliott

I pulled latest dev-branch version 1.5.10.1856, re-run installer and snapins are working again.

Thank you very much for help.

@Tom-Elliott I tried 3 snapins all returned SnapinClient ERROR: Hash does not match…

@Tom-Elliott

This is the same file downloaded from the same fog server (just with powershell iwr and saved to different folder)

Hope it helps…

@Tom-Elliott said in SnapinClient ERROR: Hash does not match:

Are you able to read the file as in a text?

Yes. See picture attached.

@Tom-Elliott The file is 16MB.

Hello,

On installed FOG dev-branch version: 1.5.10.1854 I have a problem with deploying snapins.
fogclient downloads file in C:\Program Files (x86)\FOG\tmp. The size of file is usually 1kb.
In fog log i get : SnapinClient ERROR: Hash does not match

I have checked on server sha512sum and size of installation file and it seems ok.

Any help is much appreciated.

@Tom-Elliott
This is resolved in latest dev-branch version: 1.5.10.1853
Thanks.

I have installed FOG dev-branch version: 1.5.10.1847 on freshly installed Ubuntu 24.04 LTS.

After installing and updating database I could log in with default credentials. When I tried to change fog user password i got output on picture below:

Then I tried to register host and quick host registration worked, but web output is not ok.

Can you help me with this issue?

Hello,

I have a problem when trying to register (or image) host.
I get error: e1000e 0000:00:if.6 enp0s31f6: Detected Hardware unit hang:
For more details see picture.

I have installed latest FOG dev-branch version: 1.5.10.1826. OS is Ubuntu 24.04.4 LTS.

Registration on the same laptop from different FOG server (version: 1.5.10.1763) works normally.
Any ideas?

@sebastian-roth The IP or the host name was not changed from the initial OS installation.

Solved my problem with commands you suggested to @benjamind on Apr 9, 2019, 10:49 PM.

Thanks for help.

@sebastian-roth Which version of FOG did you use before?
1.5.9.111 or 1.5.9.154 …sorry but i’m not sure exactly.

Hello,

After upgrading FOG server (on Ubuntu 20.04 LTS) to latest dev-branch version: 1.5.9.159 all FOG clients have “Middleware::Response Failed to decrypt data on server” in their log files.

Please see attached log.

Any ideas what to do…where to start?

It doesn’t help if I reinstall FOG client. The error is the same.
Does anyone have similar problem?

[quote=“Tom Elliott, post: 46691, member: 7271”]Is this a dual boot system? Why so many partitions?

It’s not a bad thing, just a bit odd to see 7 partitions.

I believe Thomas Rucker had a similar issue some time last year. His fix was documented.[/quote]

It’s not a dual boot system. Actually is a preloaded Win 8.1 from Dell.

Why so many partitions?

I have:

“System partition” d1p5.img
“Data partition” d1p6.img
“Dell recovery partition” d1p7.img

Just for info when I get a new Dell laptop/desktop and I create “Basic image” it has 6 partitions or maybe I should put it this way …i have on fog server 6 image files (d1p1.img to d1p6.img) + d1.mbr + d1.original.swapuuids…
