I have been trying to install Liquid Feedback using Ubuntu 16.04. They have instructions on their site. These things are never as easy as it should be. Here are my notes.

I am advised as follows,
This is indeed pointing to the current installations instructions. However, the repository tip may change any time to development versions in the repository. We recommend to use a release instead of the (unstable) repository tip. The current version can be found at http://www.public-software-group.org/liquid_feedback and all revisions are tagged accordingly in the repositories. Thus, the stable URL for the installation instructions for version 3.2.1 of the LiquidFeedback frontend is: http://www.public-software-group.org/mercurial/liquid_feedback_frontend/raw-file/v3.2.1/INSTALL.html
