Hello,

I am currently using the FOG REST API to develop a multicast solution for end users. Immediate multicast tasks are working as expected.

However, I’m encountering an issue with scheduled tasks. When I create a scheduled multicast task, the task object is successfully registered. But once the scheduled time passes, the task does not execute and remains listed under Tasks → Scheduled Tasks.

To rule out API-related issues, I also attempted to schedule a multicast task directly through the FOG Web UI, but experienced the same behavior.

Additional details:

Version: v1.6.0-beta.2277
SCHEDULERGLOBALENABLED is enabled
FogScheduler service is active

Could you please advise what might be causing scheduled tasks not to execute, or suggest any additional checks or logs I should review?

Thank you in advance for your help.

Hi, I installed a fresh Fog Server v1.6-beta-2303 on Ubuntu Server 24.04.4 LTS (Installation Type: Normal Server).

I used FOG Web to create a new group. The group was created successfully. However, when I selected the group to add hosts, the UI page was broken and show html format. This error is shown at the end:

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘)’ at line 8

When I checked FOG status, all services are enabled. But there are warnings related specifically:

Undefined array key “ngmID” in /var/www/fog/lib/router/route.class.php on line 2512
Undefined array key “imageID” in /var/www/fog/lib/router/route.class.php on line 2512
Undefined array key “sID” in /var/www/fog/lib/router/route.class.php on line 2512
