I just installed ownCloud on my Raspberry Pi after scouring the internets for the best set of directions. There’s quite a few tutorials out there, but only one of them worked for me, without much of a problem.
The best tute I found came from this blog:
There are two different ways to set up ownCloud using the script on the site. I had to go with Apache instead of NGiNX because NGiNX just didn’t work for some reason. But go ahead and check it out, it’s pretty nifty.
EDIT: The OS running on my RPi was Raspbian, installed using the NOOBS v1.2 .zip file found on http://www.raspberrypi.org/downloads.
