I also have this problem (with a LUKS & LVM). As a workaround, I did: 1) boot into live CD, start a terminal and do everything as root (sudo -i) 2) open the encrypted LUKS partition: cryptsetup luksOpen /dev/nvme0n1p3 nvme0n1p3_crypt
Note that the name (in my case "nvme0n1p3_crypt") must match the name that is in the etc/crypttab . Otherwise the later generated initramfs will not work correctly. 3) vgscan && vgchange -ay vgubuntu 4) mount /dev/vgubuntu/root /mnt 5) mount /dev/nvme0n1p2 /mnt/boot # this is my /boot partition 6) mount --bind /dev /mnt/dev && mount --bind /sys /mnt/sys && mount --bind /proc /mnt/proc 7) chroot /mnt 8) chmod 755 /usr/share/initramfs-tools/hooks/lvm2 9) update-initramfs -u -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lvm2 in Ubuntu. https://bugs.launchpad.net/bugs/1915579 Title: lvm2 version 2.03.11-2ubuntu1 breaks initramfs Status in lvm2 package in Ubuntu: Triaged Bug description: I upgraded lvm2 from 2.03.07-1ubuntu4 to 2.03.11-2ubuntu1 and my initramfs broke. I had to manually rollback to the old version to be able to boot. The error was something like: Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/mapper/vgubuntu-root does not exist. Dropping to a shell! And there was no neither my lvm lvs, nor lvm binary on initramfs.
