How to connect the ownCloud desktop client to your Nextcloud server

Depending on your platform, the installation will be different; I’ll show you how to install on Ubuntu 16.04. Installing the client on Windows, Mac, and Linux is an option if Ubuntu or Linux aren’t your thing (CentOS, Debian, Fedora, openSUSE, RHEL, SLE, and Ubuntu).
I work with Ubuntu but I’m having trouble installing it. Help Please!

Install instructions here:
Install package owncloud-client
