I noticed that I haven't told that I'm on buster (I took it for granted based on the package version).
On 2019-03-30 I upgraded my system and I suffer again of this bug: without explicit "insmod luks" in /boot/efi/EFI/debian/grub.cfg the boot stops in a grub shell. This packages where upgraded by the update (from /var/log/apt/history.log, purged from apps upgrades): Start-Date: 2019-03-30 20:55:36 Commandline: apt full-upgrade Requested-By: Upgrade: grub-efi:amd64 (2.02+dfsg1-13, 2.02+dfsg1-16), grub-common:amd64 (2.02+dfsg1-13, 2.02+dfsg1-16), grub2-common:amd64 (2.02+dfsg1-13, 2.02+dfsg1-16), grub-efi-amd64-bin:amd64 (2.02+dfsg1-13, 2.02+dfsg1-16), grub-efi-amd64:amd64 (2.02+dfsg1-13, 2.02+dfsg1-16), grub-efi-amd64-signed:amd64 (1+2.02+dfsg1+13, 1+2.02+dfsg1+16) End-Date: 2019-03-30 20:55:52 Start-Date: 2019-03-30 20:56:05 Commandline: apt autoremove --purge Requested-By: Purge: efibootmgr:amd64 (15-1) End-Date: 2019-03-30 20:56:05 I've tried to reinstall efibootmgr but nothing changes. I can do some tests, but I need directions. -- Mandi. Paolo
