Thanks! I'm trying to do this in openQA but it's harder to reproduce the bug at will there (I think it mainly happens when it's running lots of tests at once so this test runs slower than usual).

I can confirm <Ctrl>-<Alt>-<F2> brings me to the live desktop where the titular "Authentication Required" modal is waiting for me.

So the reason you see an Authentication Required dialog is likely https://gitlab.gnome.org/GNOME/gnome-software/-/work_items/582 - that's kinda known. AIUI, it pretty much happens any time Software decides to do its periodic check for updates, but you're not actually on the tty where the desktop session is running. The larger point here, of course, is why we wind up on tty1 (GDM) instead of tty2 (desktop). It must be some sort of race. I'll ask the desktop team to look at it.

I don't know why we have the wording allowing a login prompt, but I'm gonna argue that for Workstation the expectation/intention is that it boot directly to a desktop, *not* to a login prompt. Also reassigning to gdm, I think the packagekit error and resulting modal are just *consequences* of us landing on the wrong tty here.
