Todd and I spent a morning installing and configuring owncloud on the team server. Things worked fairly well - with essentially only one glitch that I'll discuss at the end.
owncloud was installed on a new virtual machine with Ubuntu server 12.04.3 as the initial install. Immediately after the install from an ISO image, the server was updated with the latest updates.
A web search suggested that there are only install packages for OpenSuse. Later on (more by accident) we found out that Ubuntu has an owncloud package, but we didn't use that.
