Hey Carl,
Agents can only pick up a job after they are upgraded to the version of the
server (shown in the footer of every page). So, as soon as an agent
finishes upgrading it becomes available ("idle"). It won't be able to pick
up anything till that happens.
The agent bootstrapper is the thing you actually installed (using a Debian
package, etc). It is a small component that is responsible for upgrading
the agent components (launcher and agent), which do the actual work. The
agent bootstrapper log should be in /var/log/go-agent/. The
agent-launcher.log (in the same location, on the agent machine) should have
some lines similar to this:
INFO thoughtworks.go.util.PerfTimer:53 - Performance: Downloading new
admin/agent-launcher.jar with md5 signature: WZuIEwnR+Rkpjvs4/86f4Q== took

INFO thoughtworks.go.agent.AgentProcessParentImpl:52 -
*Agent is version: 17.4.0-23620*
I don't believe the server shows the status of an agent as "Downloading" or
anything like that in the agents page.
Cheers,
Aravind
