Changelog
grub2 (2.02-2ubuntu8.19) bionic; urgency=medium
* grub-install: cherry-pick patch from grub-devel to make grub-install
fault tolerant. Create backup of files in /boot/grub, and restore them
on failure to complete grub-install. LP: #1891680
Also cherry-pick patch to make atexit work correctly.
* postinst.in: do not exit successfully when failing to show critical
grub-pc/install_devices_failed and grub-pc/install_devices_empty
prompts in non-interactive mode. This enables surfacing upgrade errors
to the users and/or automation. LP: #1891680 LP: #1896608
* postinst.in: do not attempt to call grub-install upon fresh install of
grub-pc because it it a job of installers to do that after fresh
install. Fixup for the issue unmasked by above. LP: #1891680
* postinst.in: Fixup postinst.in, to attempt grub-install upon explicit
dpkg-reconfigure grub-pc. LP: #1892526

Source diff to previous version |
1891680 |
grub-pc needs to detect when debconf points to invalid drive and stop in preinst, before unpacking files, and also treat this as a failure in postins |
1896608 |
[regression-in-stable] grub-multi-install fails with exit 1 when question grub-efi/install_devices_empty is skipped |
1892526 |
dpkg-reconfigure grub-pc no longer prompts for grub-pc/install_devices |

grub2 (2.02-2ubuntu8.18) bionic; urgency=medium
* debian/patches/ubuntu-flavour-order.patch:
- Add a (hidden) GRUB_FLAVOUR_ORDER setting that can mark certain kernel
flavours as preferred, and specify an order between those preferred
flavours (LP: #1882663)
* debian/patches/ubuntu-recovery-dis_ucode_ldr.patch:
- Pass dis_ucode_ldr to kernel for recovery mode (LP: #1831789)

grub2 (2.02-2ubuntu8.17) bionic; urgency=medium
* debian/postinst.in: Avoid calling grub-install on upgrade of the grub-pc
package, since we cannot be certain that it will install to the correct
disk and a grub-install failure will render the system unbootable.
LP: #1889556.
