This tutorial guides on installing ProjectSend, a self-hosted file-sharing software, on Ubuntu 20.04 or 18.04 LTS systems. It involves installing Nginx HTTP server, MariaDB database server, and PHP 7.4-FPM. Then, a ProjectSend database is created. The ProjectSend package is downloaded, extracted, configured and file permissions are set. An Nginx virtual host for ProjectSend content is also created and enabled. After these, the user can proceed with the ProjectSend setup wizard in their browser.
