* Do not invoke dkms_autoinstaller from /etc/kernel/header_postinst.d/dkms with redirection to /dev/null (LP: #1827697), this caused debconf dialog to not be shown. -- Julian Andres Klode <juli...@ubuntu.com> Fri, 17 May 2019 12:56:47 +0200 ** Changed in: dkms (Ubuntu Xenial) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to dkms in Ubuntu. https://bugs.launchpad.net/bugs/1827697 Title: Enroll key whiptail prompt blocks kernel header package upgrades Status in dkms package in Ubuntu: Fix Released Status in dkms source package in Xenial: Fix Released Status in dkms source package in Bionic: Fix Released Status in dkms source package in Cosmic: Fix Released Status in dkms source package in Disco: Fix Released Status in dkms source package in Eoan: Fix Released Bug description: I noticed that sometimes the system upgrade is blocked in the kernel header package's configure phase, in the process manager I found that it is blocked by the "Configuring Secure Boot" whiptail prompt started by `update-secureboot-policy --enroll-key` which doesn't surface to the terminal and hence not interactable. Refer the attached screenshot for the process status at the time. [Test Case] 1. Install any out-of-tree dkms packages (like bbswitch-dkms) 2. Un-enroll keys from MOK, ensure `mokutil --test-key /var/lib/shim-signed/mok/MOK.der` command returns "/var/lib/shim-signed/mok/MOK.der is not enrolled" 3. Ensure SecureBoot is enabled 4. Install any linux-headers-${version}-generic packages that is currently not installed, verify if it stucks at configurating state [Regression potential] Since this change will cause the output of dkms_autoinstaller to appear in the output of the kernel installs, this may surprise consumers of the dpkg log with its verbosity.
