The initial script (install-nextcloud.sh // install-nextcloud-debian.sh) will install your self hosted Nextcloud within few minutes fully automated. Your server will consist of:

Fail2Ban (Nextcloud and SSH jails)
MariaDB 10.3
Nextcloud 15 (latest)
NGINX 1.15.8 TLSv.1.3
OpenSSL 1.1.1
PHP 7.3
Redis-Server
self signed or Let's Encrypt SSL using the ssl-certificate-ubuntu.sh or ssl-certificate-debian.sh script
UFW (22, 80, 443)

The only precondition for the install-nextcloud.sh and install-nextcloud-debian.sh shell script is to utilize Ubuntu 18.04 LTS or Debian Stretch 9.x as your on-prem server OS. Optionally you may request your ssl certificate from Let's Encrypt by issuing the second script called ssl-certificate-ubuntu.sh or ssl-certificate-debian.sh.
