I have a Debian based box in my house that runs as a webserver, and a 4GB bootable usb-stick with Ubuntu. I need to store stuff on a server and Ubuntu One seems an ok way to go but I find that 2GB is not sufficient. I can most likely solve that when I install this server software. Where can I find it - there is no ubuntu-one-server package or similar in the Software Centre. How can I install the Ubuntu One server software or an alternative?
