Tails

I’ve seen My Additional Software list is configurable through a GUI or through notifications when I install or remove packages with APT or Synaptic fail because the I accept removing "sslh" from Additional Software step fails: no notification with a “Remove” button is visible on screen. That’s because the previous notification (“Additional software installed successfully”) was not hidden as planned.

As we can see in the attached video around 4:45, the click on the clock is somehow lost. That’s not a big problem in itself: if the rest of the code worked fine, we would retry, and there’s a good chance that this click would work eventually. However, despite this click not working and the calendar+notifications menu not hopening, for some reason, gnome_shell.child?('No Notifications', roleName: 'label') succeeds, even though there is a notification on screen, so we don’t try to close notifications by clicking GnomeCloseAllNotificationsButton.png (which is nowhere to be seen anyway so that would fail, but at least, it would fail closed loudly instead of failing open and breaking the following steps).

It looks like this bug is caused by Bug #12191 and then adding showingOnly: true to gnome_shell.child?('No Notifications', roleName: 'label') should fix it.

Here are the relevant debug log bits:
