installed grub2 2.02-2ubuntu8.18 and configured debconf & /boot to reproduce the issue (touched the core.img, as well as enxsured that install_devices_empty & install_devices are marked as seen, and set to true and empty respectively).
dpkg-reconfigure -u grub-pc exits zero as expected. upgraded to 2.04-2ubuntu8.19, and executed dpkg-reconfigure -u grub-pc again, and it is also successful. bionic-updates didn't have the "exit 1" bug, and it still is not there with latest round of fixes from focal. ** Tags removed: verification-needed verification-needed-bionic ** Tags added: verification-done verification-done-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896608 Title: [regression-in-stable] grub-multi-install fails with exit 1 when question grub-efi/install_devices_empty is skipped To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1896608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
