I installed FreePBX 17 PUB on local machine using SNGDEB-PBX17-amd64-12-8-0-2503-1.iso.
After installation, it successfully started, but as I missed activation part it ended up crippled so I decided to reinstall on the same machine gain. Next installation failed with error saying apache2 cannot run.
I tried reinstall several times with no success.
Then I installed it on VM on other machine and again it installed correctly, but after repeated installation I again ended up with the same error that apache2 cannot run.
After searching for resolution I learned that FreePBX on installation contacts Sangoma and sends some information, so if next time installation is attempted on the same machine, installation fails. Is that true or this is some kind of bug?
I would like to, but now I cannot even reach that point.
On repeated installation i get message E: Unimplemented function, and some time later new error that GRUB cannot be installed, so I do not even get to the point of attempting to run Apache.
On other machine, this Apache error occurred just once, after that installation never managed to finish.
I even tried OSO version, it goes south in the same way.
It not possible to install FreePBX on any of those machines any more, although, first installation went by.
This is ridiculous. I can just hope this is bug with ISO, not intentional.
Sorry to hear that. Probably GROUP setup to UEFI has failed.
Is that VM or Physical machine installation? Maybe you can try to fix Boot loader (UEFI) with Boot Debian ISO?
