FreePBX 17: On Debian 12 (Bookworm) Rasp Pi 4 unsupported version

I’ve been trying to setup FreePBX 17 with Version 21 of Asterisk on Raspberry Pi 4 4GB running Debian Bookworm. Asterisk is running fine but during the installation of FreePBX 17 when running the ./install -n command I get an error that Asterisk 21.0.0 is unsupported. I have downloaded the version in this wiki:
How+to+Install+FreePBX+17+on+Debian+12+with+Asterisk+20#Install-FreePBX

However the README in that archive says the version is 15:

root@gps:/usr/local/src/freepbx# head -n 11 README.md

This is the output I get from install:

root@gps:/usr/local/src/freepbx# ./install -n

This is the version of asterisk that is installed:

Did the tarball get mixed up?

Thanks,

The simple answer; FreePBX v17 doesn’t have Asterisk v21 support yet. Hence the install calling for Asterisk v20.

Ah I think I got confused with the versions. I’m setting up Asterisk 20 now.

Version 21 also kills Chan sip which free PBX 17 supports so they’ll have to add the logic in for that
