@johnomaz Um… well… this is a head scratch-er… because - if you completed an installation of FOG, then you should have this file. It’s where all fog installation settings are stored. This is why you are getting the errors right when the installer starts - it’s trying to read settings from that file but because it’s not there, it just throws errors for each line it tries to read.
Do you have an /opt directory? and /opt/fog directory?
