This bug was fixed in the package software-properties - 0.92.37.8 --------------- software-properties (0.92.37.8) trusty; urgency=medium
* software-properties-gtk: - fix the backend code to set the gnome debconf frontend, without which libgtk2-perl goes unused. - depend on libgtk2-perl to ensure it's available, since it was not seeded on the desktop at release time. This is only a Recommends: in zesty, but we need to ensure this isn't ignored on upgrade. LP: #1679784. -- Steve Langasek <steve.langa...@ubuntu.com> Thu, 27 Apr 2017 16:28:45 -0700 ** Changed in: software-properties (Ubuntu Trusty) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1679784 Title: Changing from Xorg video driver to NVIDIA driver using Software & Updates does not display debconf prompt Status in software-properties package in Ubuntu: Fix Released Status in software-properties source package in Trusty: Fix Released Status in software-properties source package in Xenial: Fix Released Status in software-properties source package in Yakkety: Fix Released Bug description: [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 ('dpkg -l noisy-fake-driver' shows 'iF'). 7. Reset the package state by removing the driver again. 8. Enable -proposed. 9. Run update-manager and verify that the new software-properties package is successfully installed from -proposed, pulling in libgtk2-perl in the process. 10. Close Software & Updates and re-launch it. 11. Select the 'noisy-fake-driver' package again. 12. Confirm that you are shown a debconf prompt, and the driver package installs successfully. [Regression potential] The actual code change is small and self-contained, but the fix also requires pulling in new package dependencies which will also need to be promoted from universe to main in the process. We need to take extra care to ensure the upgrade path is correct. This SRU should also be done serially one release at a time to gather feedback at each stage. [Original bug description] 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.
