Please somebody help me :( after a firmware update my Debian Sid with encrypted LUKS root does not boot clean anymore.
At boot, after inserting my passphrase, there are a bunch of messages and a timeout for like 30 seconds, and then finally I receive some yellow and red warnings about "dependency failed for /boot" and "/boot/efi". I am prompted for the root password for a recovery shell. The crazy thing is that in this shell the filesystem is mounted correctly! But I cannot start GDM3 or network.
My laptop is a Thinkpad X280 on dual boot. On partition 3 there is Windows 10, then there are three system and recovery partitions for windows, and then partition 5 is an encrypted LUKS which contains a single ext4 partition with root filesystem (including home etc, no swap). The boot drive is an external USB key which has two partitions: one to be mounted at /boot and one to be mounted at /boot/efi. I need to plug the USB key and then power on the laptop in order to boot linux, but the BIOS automatically boots Windows if a USB boot drive is not found.
Today, on Debian Sid, I did a firmware update (1.29 I think) and I guess something wrong happened. The GRUB entry 4.19.0-5 does not work anymore (complains about a missing UUID and gives me the initramfs shell, but I didn't touch the partition table!) and the old 4.19.0-4 as explained above hangs on for 30 seconds and then prompts me for the recovery shell (where, oddly, partitions are indeed mounted correctly).
Windows 10 boots correctly.
Some relevant info:
