After upgrading to Trusty (from precise) when asterisk starts I get these messages and not all functions are available:

A same bug is found at: https://bugzilla.redhat.com/show_bug.cgi?id=1009173
Loading the modules by hand works ok, why are they not loaded correctly at start-up?

Status changed to 'Confirmed' because the bug affects multiple users.

Same happens when upgrading from saucy:

[xormar (public-wernig)]

Ah, and: In my case asterisk does not start at all, so I cannot load the modules by hand. No core is dumped, it just doesn't run.

[xormar (public-wernig)]

The fact that asterisk didn't start was unrelated to this problem (had installed external modules that didn't match the new version 11).
But contrary to OP the modules cannot be loaded by hand. The same error appears:

com01*CLI> module load app_stack.so
Unable to load module app_stack.so
Command 'module load app_stack.so' failed.
[May 25 16:35:46] WARNING[5474]: loader.c:423 load_dynamic_module: Error loading module 'app_stack.so': /usr/lib/asterisk/modules/app_stack.so: undefined symbol: ast_agi_unregister
[May 25 16:35:46] WARNING[5474]: loader.c:902 load_resource: Module 'app_stack.so' could not be loaded.

[Ted Cabeen (ted-cabeen)]

Any resolution on this? This bug prevents asterisk from working with FreePBX on 14.04 without manually loading the modules after asterisk starts.

[Nick Piggott (nick-piggott)]

I'm running Ubuntu 14.04 with Asterisk 11.7.0~dfsg-1ubuntu1 and FreePBX 12.0.25.

app_stack.so will not load at boot, either autoloading or with a specific load directive in the startup scripts.

I can load it manually by connecting to the asterisk console ("sudo asterisk -r") and then manually typing "module load app_stack". It loads without errors, and operational proceeds as normal.

It's a critical problem for a remote system which is not easily remotely accessible.

[Pieter De Wit (pieter-insync)]

Here is a work around (or even a perm. fix ?)

in /etc/asterisk/modules.conf

Add the following line *before* the autoload=yes line:

load => res_agi.so

This will fix the error that app_stack needs agi to be loaded.

Tested on a clean installed 14.04 machine.

Cheers,

Pieter

[Nick Piggott (nick-piggott)]

I can confirm the workaround in #8 works for me.

Thanks, much appreciated.

[Nigel Hathaway (nhathaway)]

On 16.04 beta, doing the above just adds the error:

Error loading module 'res_agi.so': /usr/lib/asterisk/modules/res_agi.so: undefined symbol: ast_speech_change

And with systemd, it just cycles round and round trying to start:
