Error while installing (unable to detect operating system)

I am running Ubuntu 18.04 on a virtual machine on Google Compute engine and each time i try to install Cyberpanel, I get an error saying “unable to detect you operating system”, at which point the installation is aborted.

Does anyone know how to overcome this hurdle?

Please share the output of the following
cat /etc/os-release

cat /etc/os-release

My install wont go any further than that same error?

Here is my

cat /etc/os-release
