I am trying to install virtualmin via the Install Script on a clean build of Ubuntu 16.04 but am getting an error stage 22/23 on Configuring Postfix. The error I am getting is:
Error: Failed to query Postfix config command to get the current value of parameter virtual_alias_maps:
I am a little stuck in what could be causing this as it's a completely clean build of Ubuntu 16.04. I am wondering if anyone has come across this issue before with a solution?
