Steps I have tried to fix the problem:
wget https://github.com/mautic/mautic/releases/download/5.2.0/5.2.0.zip
sudo unzip 5.2.0.zip -d /var/www/html/
sudo chown -R administrator:www-data /var/www/html
composer update
composer install --no-dev --optimize-autoloader

I can notice 2 problems:

  1. You have 403 that need to be fixed
  2. Wrong user? (are you sure that it’s administrator:www-data)
  3. Using root for an install? That’s a guaranteed fail if you aren’t experienced enough (easy way: don’t use root)

it is fixed now, thank you
