how to update laravel installer 3 to laravel installer 4 in ubuntu 20.04 code example

Example 1: what are the ubuntu packages required for laravel to be installed

sudo apt install php7.2-common php7.2-cli php7.2-gd php7.2-mysql php7.2-curl php7.2-intl php7.2-mbstring php7.2-bcmath php7.2-imap php7.2-xml php7.2-zip

Example 2: laravel apache2

# Laravel includes a public/.htaccess file that is used to 
# provide URLs without the index.php front controller in the 
# path. Before serving Laravel with Apache, be sure to enable 
# the mod_rewrite module so the .htaccess file will be honored 
# by the server.

# If the .htaccess file that ships with Laravel does not work 
# with your Apache installation, try this alternative:

Options +FollowSymLinks -Indexes
RewriteEngine On

RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
