There is a tarball: https://nextcloud.com/install/#instructions-server
Since it looks to be written in PHP, it doesn't need to be built and you don't need a special ARM version for that Pi.
I'm guessing it plays nicest with apache. In any case, Nextcloud has documentation for the server. Raspbian is a form of GNU/Linux, so you will want things that ...
By installing a NFS server on the other server with 2TB storage you can export a directory of this server and mount it on the raspberry pi.
To install the NFS server on Debian (or raspbian) follow e.g. this tutorial https://linuxconfig.org/how-to-configure-nfs-on-debian-9-stretch-linux or any other tutorial on the web.
The ArchWiki also has good ...
This is a futile endeavour. The System requirements for Document Server include:
CPU: dual core 2 GHz or better → while Raspberry Pi 2 & 3 have quad-core processors, they're ~ 1 GHz ARM quad core. Server spec software usually assumes Intel power per core
RAM: 2 GB or more → the most RAM that a Raspberry Pi supports is 1 GB
OS: 64-bit Debian, Ubuntu or ...
You can't access the data directory locally, nextcloud will complain if you change the permissions or add files directly as an anti tampering measure. To do what you describe you'll need to use webdav and mount nextcloud as a webdav share on the pi and then you'll be able to save files straight to it via that folder.
I've bought one; received it 10/24/16. Unfortunately, I cannot log in through the web interface as the system instantly closes the connection after I enter my userID/password combo and click to enter or press an enter key. I can log in via SSH with Putty, but that's not exactly how I'd like to do things. Haven't had time to find the cause of this issue, and ...
Segmentation fault is a major software error, caused by invalid memory addresses in the code. It is not something you can typically cause as a user through normal fiddling using standard packages . Except in extremely rare cases where it is a bug that is exposed by something you do.
Assuming you are using repository packages and not compiling from source ...
If you see ONLY a 32Mb drive the SD Card is faulty. This has happened to me once, and a few others. I contacted Sandisk concerning this.
You should return the card to be replaced under warranty. You are truly unfortunate to have this happen twice. It is a rare fault.
On GitHub tere is a install script (Shell) for NextCloud on Raspberry Pi.
This is the build code for NextCloudPi.
NextCloudPi is a ready to use image for Raspberry Pi.
This code also generates the NextCloudPi ARM docker image.
I've just set mine up for anyone else that comes across a build like this...
-Rpi3 connected with RJ45
-Samsung Evo plus SD card
-WD 1tb Pi Drive
-Ubuntu Snappy Core
-Asus 1200ac Wifi Router
I got about 100 MB/min write performance locally (from my computer to NextCloud), which to me is plenty for a low cost cloud that I have complete control over.
