Error on Installation

Hi, I am getting an error after putting in the hostname for the installation process and this is what I am getting. Im not sure what is causing the issue since i checked and the 3 are installed

 subprocess installed post-installation script returned error exit status 1

You have entered wrong value for your host, should not be https… But just the dns. Uninstall using the command from the doc and try again


I did the process again and successfully there were no errors @damencho. However, it only shows grey screen and says interfaceConfig not defined on the console.

I tried to enable SSI by following these steps:
• edit apache2.conf
• sudo a2enmod include
sudo a2enmod include.load
• edit 000-default.conf in sites-available
• restarted apache2 service

But still same error shows up. Im not sure though if these steps enabled the SSI
