Automatic update notifications in Debian Testing

Automatic update notifications alert you to security and other updates that can be installed- and it's good to be made aware that these updates are available.

As I have pointed out before, automatic update notifications were broken in Debian Jessie, they apparently were fixed, but didn't work for a lot of people including me, they were fixed in Debian Testing, but didn't work for me after a recent update to Testing (Stretch) on this laptop.

I have now discovered that automatic update notifications are working in Testing- I just needed to enable show-upgrade-prerelease in dconf-editor.

After doing that, I started to see notifications.

As I wrote about previously, updates are now done offline in Gnome.
