I am using the Virtualmin GPL installer, version 8.1.2 (so I assume it is trying to install the latest versions of webmin and virtualmin) on a Grade B OS (Ubuntu 26.04) with the recommended automated script.
It is on a UTM virtualmachine on a Mac and is only intended as a test server at home, so no internet domain exists.
It stops at this point with the message:
[ERROR] Your system hostname gjj-QEMU-Virtual-Machine is not fully qualified. Please enter a fully qualified hostname (e.g.: host.example.com):
How do I convert the hostname to a FQDN for this installation? Just add .local?
I do not want to wing it and end up having to start all over so guidance please?
so a FQDN is made of 3 parts and is used to identify the server on the internet.
The domain needs to be a real domain name because you expect your server to do email and the internet needs to be able to contact your server. But you can choose a fake one and change it later, just somethings might not work as expected.
