This is the first I've heard of N1. It looks appealing, but after following the links and looking at it on GitHub, it seems like installing the sync server for self hosting is still non-trivial.
I went to the "releases" tab on GitHub and it looks like the last one was in 2014. I see things in the GitHub repo that suggest there are Dockerfiles and Debian packages, but I don't see an actual Debian package repository or an entry on the Docker Hub. Is the recommended way to use it today just cloning the git repo? Or is there a stable release of the sync server that's tested/known to work with the binaries of the client?
