One of the solutions is to download manually the missed package. get_extra_file usually followed by the package link that monasca-api cannot download. Use these steps to resolve the issue:
1. Download the packet: # wget package_link
2. Comment all lines related to downloaded packages in monasca-api/devstack/plugin.sh
3. Replace the variable_dst at installation line by the local file that you already download.
Example if the issue is with kafka: go to line 311 of plugin.sh and replace sudo tar -xzf $kafka_tarball_dest by sudo tar -xzf ~/kafka_2.11-0.9.0.1.tgz
