Could you please run: sudo debconf-show grub-pc sudo debconf-show grub-efi-amd64
I've attempted to reproduce this; by first downgrading to a previous version, changing settings in /etc/default/grub, and proceeding with the upgrade, but no matter what I do, the changes do remain in /etc/default/grub. I've tried simply setting i915.modeset=1, but also reverting again (so i915.modeset=1 is present in debconf to begin with) and adding another entry to be in GRUB_LINUX_CMDLINE_DEFAULT; and also the same with GRUB_LINUX_CMDLINE. As far as I call tell, the update works correctly, so we need to look if there's anything special in the debconf database in case that would affect the behavior. Note for developers: the ucf code is only in grub-pc.postinst or grub- efi-amd64.postinst; so this affects those packages rather than grub(2?)-common. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823259 Title: Update from grub-common AMD64 2.02-2ubuntu8.12 to 2.02-2ubuntu8.13 removed some Grub settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1823259/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
