我在我的 Ubuntu SSD 驱动器上使用 LUKS + LVM。
我尝试使用 livecd、mount、chroot 和更新 initramfs + grub 进行启动，但这并不能解决问题。

几个小时后，我找到了解决方案......只需安装新的内核版本，之后我就能成功启动。
完整命令列表：
# My ubuntu uses LUKS + LVM with separate boot partition
# sdc - my SSD in LiveCD
# sdc5 my root partition name in LiveCD
# sda5_crypt - should be same as in /etc/crypttab in system for restoring
sudo cryptsetup luksOpen /dev/sdc5 sda5_crypt
sudo mount /dev/mapper/ubuntu--vg-root /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
# Mount boot partition
sudo mount /dev/sdс1 /mnt/boot
# chroot to /mnt
sudo chroot /mnt
# Install new kernel

启动系统后，我运行了更新检查并安装了“5.15.0-69-generic”。
祝你好运！
