Installing NextCloud Server on Ubuntu

Nextcloud is open-source software, first developed in 2016, that allows you to run a personal cloud storage service. It has features that are comparable to other services such as Dropbox, Google Drive, OneDrive, etc. The Nextcloud server software can be installed free of charge on Linux, and the client software can be installed on computers running Windows, OS X, or Linux. Mobile apps are also available for Android and iOS. Nextcloud is a fork of the OwnCloud project, developed by many of the original members of the OwnCloud team. The two projects have many similarities but differ in their interface, as well as in their respective licensing agreements, especially for Enterprise editions.
