Bug Description

This server doesn't work at the minute.

When advancing to the last page of the wizard, the following message is displayed:

** (gnome-initial-setup:803): WARNING **: 13:44:36.643: Failed to send decline: data were not delivered successfully to metrics server: couldn't send post http request: Post https://metrics.ubuntu.com/ubuntu/desktop/18.04: dial tcp 127.0.0.53:53: i/o timeout

and there is a delay of a few seconds displaying the page.

I suppose the calls to sysmetrics to send the report/decline should be done asynchronously. It's probably not a big problem if a few people manage to quit before the submission is finished, but if it is then there would need to be a way for the quit button to wait for all save calls to finish their async work.

@didrocks - is libsysmetrics thread-safe? I guess I should just wrap the call in a thread?

libsysmetrics is using multiple goroutines (and potentially threads), but all the external API is thread-safe, I took care to not do any operations which can change the global state for that purpose.

I think “Continue” should advance immediately to the next step, regardless of how long any submission takes or whether it fails. The user is doing us a favour by submitting data, and there’s no need for us to bother them at all if it happens not to work. It’s not as if we’re desperately short of submissions.
