While installing FreePBX on a physical workstation, I receive the following error. Is there anyone who can guide me through the installation process on a physical workstation ?
What do you mean by a physical workstation? The real difference is in usage and and software configuration, but mainly in usage.
If you are getting a panic during installation, you have a faulty OS, faulty key device driver, or mismatched OS and hardware. The only part of Asterisk/FreePBX that could normally cause a panic on a good platform is DAHDI, and you seem to be too early for that.
Either the exception type is off the top of the screen, or needs an analysis of some of the registers.
I mean we try to installing on desktop (Model : Dell Optiplex 7010) and i downloaded ISO from Freepbx portal.
check your memory
This sounds like an issue with the hardware. Also there is no longer an ISO for FreePBX. You first install Debian 12.5 on your hardware and then run the FreePBX 17 install script to install FreePBX.
