error: 'AgentConfig' object has no attribute 'plugin_path'

You may get this error when trying to install a plugin.

This article is for our v1 agent and will soon be deprecated.

error: 'AgentConfig' object has no attribute 'plugin_path'

This is because you do not have a plugin_directory value in your /etc/sd-agent/config.cfg file. Just edit the file and add it in, providing a path to your plugin directory. You should create the directory somewhere where the agent has access to it, e.g. /usr/bin/sd-agent.
