Unable to install Sysadmin after 15 to 16 update "In Install.php line 17" Errorc

I am running into an issue where sysadmin will not install. I get error:
In install.php line 17:/etc/sangoma does not exist. Can’t continue

Running yum install sangoma-pbx gives:
No package sangoma-pbx available.
Error: Nothing to do

Any ideas?
