Thanks for writing this up! This worked almost perfectly for me on 17.10 as well!

Three things of note:

1. In dependencies I had to add: sudo apt-get install libmsgpack-dev
2. The directions for installing msgpack aren't quite right. This worked for me:

cd /tmp
git clone https://github.com/msgpack/msgpack-c.git
cd msgpack-c
cmake .
make
sudo make install

3. On Ubuntu 17.10 it wasn't necessary to upgrade LibSSH, for whatever that's worth :)
