I am using LUKS + LVM on my Ubuntu SSD drive.

I tried to boot using livecd, mount, chroot and update initramfs + grub, but that doesn't solve the problem.

Marking to close this based on the hostname being "mint" suggests this is a Linux Mint system which is unsupported here. Do let me know if this is an incorrect assumption.

I'm using Mint as a livecd

After few hours, i found solution... just install new kernel version, after that i booted successfully.

Full commands list:

# 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
cd /home/username
mkdir kern
cd kern

After that I get this log:

After booting into the system, I ran an update check and installed "5.15.0-69-generic".

Good luck!

You have installed an unsupported kernel. This will cause you issues with upgrades.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
