Test and Document Install steps for popular setups
We need to test documented installation steps for popular setups, like;
- Ubuntu 16.04 (pip method failed badly, because of python2)
- Ubuntu 18.04 (pip method failed, apparently needs more packages on host)
- Ubuntu 18.10
- Debian 9
We should also update instructions for systems above.
Example; Ubuntu 16.04 (or any python<3.6 users) should just use the binary distribution.
