I did try Google, of course, but the fix was not apparent to me. And besides, now the Raspberry Pi that it's running on is not responsive at all. Nothing I do will allow me to access the user control panels.
Raspi-config turned up an error trying to do an update. And in booting the Pi I get the message that "Not starting asterisk with incorrect system time" (or something like that) and then something like "astrundir in etc/asterisk is set to /var/run/asterisk but the directory does not exist. attempting to use mkdir -p /var/run/asterisk". I then got the usual raspbx log in prompt and created the directory myself, but it still does not work.
