Do you have DAHDI hardware? It looks like your DAHDI software setup is going, but the hardware doesn’t seem to be responding.

Unfortunately that is not the issue. The error about key not available is generaly related to compilation issues due to kernel mismatch, which is very strange because I didn’t compile DAHDI by myself, it is the version installed by the SNG7 installer.
In any case, DAHDI should load even without any cards installed.
In fact, with FreePBX Distro 10.13.66.18 on the same server, without any cards installed, DAHDI loads with no errors.

Hi!

Can you try

What are your results?

If you get the same thing described in the message that follows, try this:

(which is, by the way, safe, @GameGamer43 confirmed it…)

Good luck and have a nice day!

and the few messages that follow

Unfortunately, it doesn’t solve the issue, I think there is a kernel mismatch, even though this is a default installation and no manipulation of the DAHDI package as been done.

Hi!

I have an upgrade from the old Centos of FreePBX 13 to Sangoma 7 but we are using the same repos, should have access to the same packages so this seems improbable…

I am not saying it cannot be caused by that but the first matches I get for this error on Google are issues about key signing and having activated secure boot in the BIOS…

That would make sense since those modules are most likely not signed…

My guess is the old distro didn’t care about secure boot and didn’'t check for this…

Can you please check if “secure boot” is activated in your BIOS?

Good luck and have a nice day!

Nick

Thanks for the tip, but secure boot is not enabled.

Hi!

Unless @GameGamer43 has an idea, it might be time for a ticket…

It definitely felt like it could be secure boot related, I wonder what other kind of “key” they are referring to…

The requirement for signed modules is configurable at the kernel level as far as I can see but we are supposed to have the same kernel (what does uname -r gives you?) so if it was set at that level we should both have the same issue.

Of course, I don’t use a Digium card but a Sangoma one (an A200 to be exact) but it should warn me when I try to load one of these modules if I had the same problem…

Good luck and have a nice day!

Nick

I have the same kernel as you. It shouldn’t matter which card you have, even without a card that error should not be happening.

10

@arielgrin Did you ever find a solution?

11

In that moment, I think I just kept using FreePBX 13 distro if I recall correctly. Are you experiencing that issue now?

12

Yeah along with another strange issue, asterisk keeps crashing, but the gui doesn’t show it in the dashboard status.

13

Can you post the error that you get? Which version of the distro? Which card? Does this error just started happening or happened since the server was initially installed?

14

cat /etc/schmooze/pbx-version
12.7.6-1904-1.sng7
no cards installed but as you said dahdi should load anyway,
the issues started like 2 days ago, the only error I found so far is the same as you got from dahdi.

15

Are you saying that the error just showed up from nowhere, or have you updated anything?

16

Yes I updated modules a few days earlier

17

Just modules or did you update anything with yum update?

18

You got me, yes I did a yum update but I think that was after the issues started.

19

You could always try to reinstall DAHDI with yum.

20

It looks like a UEFI issue.
