I recently investigated Nextcloud (despite it being one of the "available" Plugins and having run FreeNAS for a couple of months) and I'm very eager to deploy on my server. I was able to install Nextcloud 10 via Plugin / Jail quite easily (without doing any research or following a guide), but was somewhat disappointed when I learned that PHP must be upgraded to 5.6 to install Nextcloud 11. This prompted further research on how to deploy Nextcloud 11, with some of approaches looking a bit...
