Nevermind... It was a partition size problem. I had expanded the partition, but not the logical root one. All seems to be running now that it has plenty of space.
Thanks. I ran the script, and similar to @Jebs2k above, it was a fresh incrediblepbx 13-13 install.. now asterisk/mysql won't start now. I'm on a RasPi 3B+. I decided to try another reboot and this is what it reported:
root@incrediblepbx:~# reboot
