Owncloud

Here is a guide on how to install the free and open-source (FOSS) “Dropbox” alternative. We will install Owncloud on a MySQL / Apache / Ubuntu server which is the most commonly used way of using Owncloud.
The Owncloud organization provides an Enterprise server which will bring you mobile branding and support. The base of the product Owncloud Server (Community Edition) is FOSS. The community is active and provides good working apps for common tasks.
On the Owncloud website you can find the Owncloud client to install on your computer (Windows / MacOS / Linux) and the links to the tablet/smartphone clients.
