OK, somehow you've elected to use LVM and an encrypted swap file .. I wouldn't have done this, and can't say for sure how it will affect things.
If I were you I'd start again and NOT use LVM .. but we can attempt to stop the filesystem check dialog .. run:
that will force a run of the file system checker (fsck) at next boot .. hopefully this will automatically fix any errors.
If you still get the same message, hit the "M" key for manual recovery, cross your fingers, and accept any suggested changes.
Once finished, see if it boots without that message.
