Verbose_extension_update_notification.png

On my Arch Linux installation with GNOME 3.24.2 I have found that if my system can't check for updates to my GNOME Shell extensions due to the lack of an internet connection that I get a rather big and unnecessarily verbose notification:

This might be useful in a log, but certainly not in one of these notifications. This is really debugging information, it is only likely to confuse and concern normal users. In fact, I don't think that the solution would even be to make the message more user friendly, but I think that although this could be recorded in a log somewhere, that actually it should just fail silently given that it's not a very important thing and could just try again in 5 minutes or something. For instance, when gnome-software checks for updates it doesn't display something like this, but rather fails silently and then tries again later.

I am not entirely clear on which application deals with this, so I'm just going to put this bug initially under gnome-shell, please move it to the appropriate place, unless that is it of course.
