Error trying to enable dahdi dummy


Running ASL 1.01 on a raspberry pi 3b here, I was recently reading the instructions for dahdi dummy and hoping it would resolve some audio stuttering issues… I’m getting stuck where it says you do not appear to have the sources for the kernel installed. Having next to zero linux knowledge (I’m a windows admin) I don’t want to break anything further… Is my kernel too new, or what is happening here?

sudo apt-get install linux-headers-uname -r -y


sorry - copy/paste did not work right: there should be single quotes around the

uname -r

and no space character before the first quote
on my system this is


Found the correct command by googling off of what you posted, and this is the error I’m getting:

root@simulcast:~# sudo apt install linux-headers-$(uname -r)

E: Couldn’t find any package by regex ‘linux-headers-4.9.80-v7’

yeah … that is a later version than what I am using. You could try downloading the header files I used and see if that works for you (if you don’t mind trashing your setup should it not work). I am not an expert in this but I base my suggesting on this:
