I followed the procedure stated on Question 4 under the AllStarLink Wiki onto my Raspberry Pi 3B+ with Debian Stretch. First signs of deviation from the normal output I saw that, since I had installed the CompassLinux repository to install ambeserver, as I gave the command to install the raspberry pi kernel headers, the kernels had the compass attached to the version numbers of the archives being installed. I configured the node for dahdi/pseudo use. I ran the command asterisk -c to see the initial output, output below.

Do I need to flush everything and start fresh, or is there a procedure for Raspbian Stretch I need to follow? Many thanks. Jose Roberto Ruíz García Salas TG9AOR
