How to Install OwnCloud on Ubuntu 18.04

OwnCloud is a leading open-source file sharing and cloud collaboration platform whose services and functionalities are similar to those offered by DropBox and Google Drive. However, unlike Dropbox, OwnCloud does not have the datacenter capacity to store hosted files. Nevertheless, you can still share files such as documents, images, and videos to mention a few and access them across multiple devices such as smartphones, tablets, and PCs.
