Ghost install did not create system/nginx-root folder

[mawann]

The ghost install went perfectly without any errors. But at the end of the installation process, the system/nginx-root folder was not created.

I am using:
Ubuntu 20.04.6 LTS.
mysql Ver 15.1 Distrib 10.3.38-MariaDB
Node.js v16.20.0.
Ghost-CLI version: 1.24.0

mawan@vps:/var/www/domain.com/ghost$ ghost install

Ghost was installed successfully! To complete setup of your publication, visit:

https://www.domain.com/ghost/

When I tried to open https://www.domain.com/ghost/, an error message appeared: 404 Not Found

I checked the contents of the folder.
This was the result.

mawan@vps:/var/www/domain.com/ghost$ ls
config.production.json  content  current  versions

There was no system/nginx-root folder!
This was what appeared when I run Ghost Doctor.

mawan@vps:/var/www/domain.com/ghost$ ghost doctor

I reinstalled Ubuntu then reinstalled Ghost from scratch. Problem solved.
