[Bug 1244211] Re: system-image-cli hangs indefinitely at "Running group download reactor"

[Barry Warsaw]

That looks like a problem with the download service not sending us the
necessary signals.   I'll bet it's unreproducible right? ;)

Eventually, the reactor would timeout anyway (default is 10 minutes),
but that probably wouldn't help you debug this much.  If you wanted to,
you could set the environment variable SYSTEMIMAGE_REACTOR_TIMEOUT to
some huge number of seconds and see if it's just a slow network
connection.  While you're doing that, tail /var/log/system-
image/client.log for details about system-image-dbus and (I think)
/home/phablet/.cache/ubuntu-download-manager/ubuntu-download-manager
/ubuntu-download-manager.log (!) for details about what's happening in
the dl service.

Best guess is that it's just an intermittent networking problem.
