Forget LUKS passphrase

Hello, I forget my LUKS passphrase. Is there any other option beside installing new OS?
I thought of removing only the affected partition, but is it possible? If yes, how to do so?

Can you boot from a live USB and post the output of lsblk command?

I use camera to post here since I do not have clue to copy the result from terminal in emergency mode.

If sda1 and sda2 is your efi and boot partitions and sda3 is your LUKS container which includes both system and user’s home directories (I forgot to mention -f option to lsblk command in the above reply, which would show filesystem information and would print crypto_LUKS for the LUKS container), you need to wipe sda3. If you didn’t backup your LUKS header somewhere else, it is not possible to recover a lost LUKS password.

Yes, crypto_LUKS is stated in sda3. How to wipe my sda3 then?

Just perform a new installation using the whole disk.
