The above was an issue reported by @mifu7913.

It seems like you didn’t create an Apache Vhost file or the name of the configuration file is different.

• To create a vhost after apache has been installed I’ll recommend checking the following article

https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-ubuntu-18-04#step-4-%E2%80%94-setting-up-virtual-hosts-(recommended)

It’s already added to the intial tutorial but in case you missed it, please do check it out.

• Chaning the name of the configuration file

mv /etc/apache2/sites-available/your_domain.conf /etc/apache2/sites-available/NewName.conf

Please be sure to change the your_domain.conf and NewName.conf with the real values.
