Public bug reported: Since upgrading from Focal, it seems that I'm hitting boot problems every time Grub is ugpraded.
For context, I recently upgrade from Focal to Groovy, then on the same day, to Hirsute (prerelease). On the upgrade to Groovy, my system stopped booting to grub, and I needed to load a Groovy install USB and run "grub-install" to make my system bootable. (More specifically: grub-install --uefi-secure-boot --boot-directory=<mounted /boot> --efi-directory=<mounted /boot>/efi) On the upgrade to Hirsute, the same thing occurred, and I had to repeat the same to be able to boot. And after package upgrades yesterday, when I powered on my machine today, the same thing occurred again, so I gathered some details this time around. The following grub packages changed during last night's upgrade: grub-pc-bin:amd64 (2.04-1ubuntu40 -> 2.04-1ubuntu44) grub-efi-amd64-signed:amd64 (1.163+2.04-1ubuntu40 -> 1.166+2.04-1ubuntu44) grub-efi-amd64-bin:amd64 (2.04-1ubuntu40 -> 2.04-1ubuntu44) grub-common:amd64 (2.04-1ubuntu40 -> 2.04-1ubuntu44) grub-pc:amd64 (2.04-1ubuntu40 -> 2.04-1ubuntu44) As context, my system uses EFI (secure boot on if I recall right), and my disk is partitioned as follows: Device Start End Sectors Size Type /dev/sda1 2048 1050623 1048576 512M EFI System <- /boot/efi /dev/sda2 1050624 2549759 1499136 732M Linux filesystem <- /boot /dev/sda3 2549760 500632903 498083144 237.5G Linux filesystem <- / (encrypted LVM) /dev/sda4 500633600 500666367 32768 16M Microsoft reserved /dev/sda5 500666368 999149401 498483034 237.7G Microsoft basic data /dev/sda6 999149568 1000212479 1062912 519M Windows recovery environment Also, note that simply doing "sudo update-grub" does *not* trigger this problem. It seems to be something which happens at upgrade time. Please let me know if there's any other info I can gather for this; I fully expect this problem to recur the next time grub gets upgraded as well. ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918314 Title: Cannot boot from grub after upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1918314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
