For several days now, I've been reading and trying a lot to install a Nextcloud server on my Pi2B. Unfortunately, I have not been able to find a clear tutorial for this installation, as I am quite a newbie. For instance, most of the posts/docs ask to chown data folder or to perform some other commands which are not allowed in LibreElec, from what I understand.
So what I would like is to install Docker (done) then Nextcloud (done) on my Pi, but I can't manage on using my external hard drive (plugged to the Pi via USB and automatically mounted on "/media/My Book") as my Nextcloud data folder. I understand there are some operations to perform before launching the Nextcloud web interface ? Not sure...
Could someone help me with that operation?
