"Unable to get subsection" error with RC-4

JoeG · Jul 27, 2016, 6:16 PM

After upgrading to FOG 1.3.0-RC-4 I am seeing the following errors on imaged computers. I have tried resetting encryption data for the hosts but no change. Apache2 logs are filled with the error message below.

Suggestions, support appreciated. Thanks,

Joe

Could that host have .Net 1 installed on it. Just a shot in the dark

JoeG · Jul 27, 2016, 6:58 PM

@Psycholiquid Nope, no .NET on host

Wayne Workman · Jul 27, 2016, 9:59 PM

I’m not entirely sure that apache error was caused by this. The timestamp on the error says 1:20 PM and the timestamps in the fog log are from 11:54 AM.

It looks like the apache error is from trying to list members of a group, or listing groups. Who is 192.168.35.155 ?

Tom Elliott · Jul 27, 2016, 10:06 PM

If no .net, what if you install .net 4.0?

Wayne Workman · Jul 27, 2016, 4:14 PM

@Tom-Elliott I don’t think it can even be installed on anything that doesn’t have 4.0 or higher. I think I tried with Win7 when the smart installer came out - and it didn’t work, and I said screw it because it works out-of-box with Win10 with nothing additional installed - and we were going to 100% windows 10.

JoeG · Jul 28, 2016, 12:14 PM

@Tom-Elliott With .Net 4.5 on the image/host this error persists. Updated logs coming soon

Tom Elliott · Jul 29, 2016, 1:26 PM

Did you restart after installing .NET?

Bob Henderson · Jul 28, 2016, 1:29 PM

Also getting this same issue, Windows 10, RC-4 with client 0.11.3

Wayne Workman · Jul 28, 2016, 7:38 AM

@Bob-Henderson said in "Unable to get subsection" error with RC-4:

Also getting this same issue, Windows 10, RC-4 with client 0.11.3

All hosts operating under RC-4 should have 0.11.4, and anything older should auto-update.
We need your fog log.

Bob Henderson · Jul 28, 2016, 7:46 AM

Alright, here’s a chunk of the log, as it’s too long to post here in it’s entirety. Note, this image was originally captured on 8533. The server has been updated to RC-4 since then.

Tom Elliott · Jul 28, 2016, 1:52 PM

@Bob-Henderson Do me a favor (and hopefully yourself) and run “Reset Encryption Data” on the hosts giving this issue?

Bob Henderson · Jul 28, 2016, 2:01 PM

@Tom-Elliott

no dice. Same errors.

Tom Elliott · Jul 28, 2016, 2:03 PM

@Bob-Henderson Did it cycle back over in the log and you’re still seeing the same issue?

Can you post a log of the host you just reset encryption data on?

Bob Henderson · Jul 28, 2016, 2:22 PM

@Tom-Elliott

looks like I needed to just give it a moment. I went down to take a look at it again, and it had joined the domain and all was hunky dory. I just reset the encryption on the other host that was giving me the same issue, and it joined right up as well.

Now, is there any way to not have to reset the encryption per host manually? I’m looking at 700 hosts to image out, and while it’s doable, it’ll be…tedious.

Tom Elliott · Jul 28, 2016, 2:24 PM

@Bob-Henderson You can reset data to all hosts through groups.

I don’t know why it’s not getting the right codes. That I need to work with @joe-schmitt as I’m pretty sure we have code in place to prevent this issue.

Bob Henderson · Jul 28, 2016, 2:26 PM

@Tom-Elliott Perfect. Thanks so much.

Psycholiquid · Jul 28, 2016, 2:41 PM

@Bob-Henderson I have a group setup with all hosts in it and hit reset encryption there is I need to do for all. It is a quick and dirty way to do it.

Bob Henderson · Jul 28, 2016, 3:02 PM

@Psycholiquid Just did the exact same thing, and pushed out an image multicast to 46 devices in 13 minutes, from start to being able to login.

best. Feeling. Ever.

Psycholiquid · Jul 28, 2016, 3:03 PM

@Bob-Henderson Thats because @Tom-Elliott and the other devs rock here at FOG
