Upgrading FOG

[jfernandz]

Hi everyone, I’m trying to upgrade my FOG server instance, but particularly I also need to recreate my CA and server cert, so what I’ve tried is:

• git fetch --all in my fogproject clone of the github repo
• git merge (over the stable branch, ofc)
• then I’ve run bin/installfog.sh -C -K

All seems to work properly, I can even register HOSTs without problem, but … When I try to capture an image of some HOST I just can see a lot of

* Attempting to check in............................Failed

I’ve been searching for similar issues in the forum and I saw a few posts, of course I’ve checked my FOG_WEB_ROOT is properly set to /fog and indeed it is. In fact, I’ve not touched this setting and before upgrading it was working properly, so I’m not sure what could be happening in the upgrade process.

Thank you very much guys.

Ok, definitely I think I’ve found the issue. Apparently the problem is caused by this feature of forcing the task,

if I let the client to restart the machine at the time the task is scheduled or if I restart manually the machine … this problem doesn’t arise.

Why do you this this feature is causing these attempts to check in to fail?

@jfernandz When you see this error (Attempting to check in … Fail) can you also look at your http/php error logs and see if anything is logging there?

I’m not aware of anything problematic due to the ability to “Force task”. Are you forcing the task and it’s causing the issue or just the ability to “Force task” is causing the issue? Just trying to understand.

@Tom-Elliott sure, I’m forcing the task and this is causing the issue, just the ability or feature “force task” by itself doesn’t cause the issue, is just when I use it, if I let the task to be run by itself in the scheduled time or if I reboot the machine manually the capture is performed as expected.

Let me check the apache logs when this issue arises.
