Nextcloud is an open source software package providing remote file sharing services. It is similar to Dropbox. But with Nextcloud, you retain ownership, security and control of the shared data. This procedure describes how to build a working Nextcloud service using just 3 commands. It has been tested on Raspbian Stretch and on the Raspberry Pi 4 / Raspbian Buster (this article updated 9/8/19)
Note: If you would rather do the installation manually, step-by-step, without the help of a script, please see my previous article “Simple Nextcloud Installation on Raspberry Pi“. It explains how to do the installation in detail, and provides more background information on Nextcloud. Both procedures achieve the same overall result, however.
Note: If you are running Raspbian Buster, then Nextcloud 16 will be installed. For Stretch, it’s Nextcloud 15.
