    lvm swap parition encrypted by luks doesn't boot

    The problem is that I can boot into /boot (GRUB2 and unencrypted) and / (/dev/sda6), but swap (/dev/sda7)
    It didn't even ask me the paraphrase to unlock swap partition.

    lsblk -l
    Code:
    NAME   FSTYPE    LABEL           UUID                                 MOUNTPOINT

    Did I miss anything so that everybody won't give their hands on my thead?
    Should I do anything?
