I don't think this test case is well formed, it doesn't describe how to install the packages with the named backends and it doesn't mention needing to kill the frontend or when to kill it.

[Solution] The solution is to move the end point into a socket-activated systemd unit, so that it is independent of the graphical frontend that started the transaction. The other advantage is that this offers us restart if the end point crashes. [Test case] 1. Install opera deb using packagekit, ensure service is activated 2. Install opera deb using aptdaemon, ensure service is activated Alternatively, you might use another deb that has debconf prompts. [Regression potential] Systems that do not yet use systemd will fall back to the old method, so should not regress. Otherwise, if there are bugs, they'd affect the ability to show debconf prompts, and behavior would revert to using the defaults. There might be some uncertainty if you restart your desktop while the helper is running and it does not pick up the new X/Wayland display until it restarts (it should fail to connect and restart). Given that the helper times out, this should not be an issue in practice, as you'd have to logout, login, and start a new install within 60 seconds.
