İspconfig Does not install automatically

Hello friends,
Ispconfig gets stuck as below when I try to install ubuntu 18 on a device with automatic installation.
What could be the reason for this?

Code:

Time zone:                Europe/Istanbul (+03, +0300)

Virtual Machine (VM) hypervisor:    kvm

Installing for this Linux Distribution:    ubuntu-18.04
Is this correct? (y/n) y

Preparing to install... [DONE]

Updating apt package database and upgrading currently installed packages...

it does not output any errors, it just stays this way.
I wait for hours like this, but there is no change.

 

I finally found the solution

hola Larkolag tengo una duda sabes si ispconfig es compatible para ubunto20.04 ?

 

It is not.
However, not yet published ISPConfig 3.1.16 is compatible with Ubuntu 20.04.
