** Description changed: + [SRU Justification] + software-properties does not display debconf prompts. while most debconf prompts have default answers and this is fine, for installing dkms modules on a SecureBoot-capable system we specifically have a critical debconf prompt with no possible default answer that users need to step through in order for their dkms modules to be usable. + + [Test case] + 1. sudo apt-add-repository ppa:vorlon/debconf-tests + 2. sudo apt update + 3. Launch Settings -> Software & Updates -> Additional Drivers + 4. Confirm that you are offered the option of using the 'noisy-fake-driver' package. + 5. Select this driver and apply changes. + 6. Confirm that no debconf prompt is shown, and the driver package fails to install. + 7. Enable -proposed. + 8. Run update-manager and verify that the new software-properties package is successfully installed from -proposed, pulling in libgtk2-perl in the process. + 9. Close Software & Updates and re-launch it. + 10. Select the 'noisy-fake-driver' package again. + 11. Confirm that you are shown a debconf prompt, and the driver package installs successfully. + I've encountered this repeatedly. In the first installation -- on updating via Software Updater, this crashed on upgrading the shim-signed package. On suggestions from here: I upgrade the system via CLI, i.e. dist-upgrade. This seemed to work, however when I now try to swap the display driver, from xorg --> nvidia. This now triggered the same issue.
