Hi @rex
before installing bagisto, you need to install all the above mention PHP extension.

• curl install link https://www.cyberciti.biz/faq/how-to-install-curl-command-on-a-ubuntu-linux/

• Install intl extension https://stackoverflow.com/questions/42243461/how-to-install-php-intl-extension-in-ubuntu-14-04

Also if you're installing bagisto 1.2.0 version then make sure PHP v7.4 should be installed.
