# Install Ryu
# We're installing a fork of the official Ryu repository because
# the official repository won't work on Ubuntu 22.04
# (https://github.com/faucetsdn/ryu/issues/169). In the
# long term, we should switch to a different controller, since
# Ryu is no longer actively maintained.
