the first thing is to make a header-backup if you do not alredy
have one. It is too easy to do damage when experimenting in such a
situation. Instructions are in FAQ Item 6.2 here:
That said, cryptsetup should complain on a defective header, so
that does not seem to be it. It could be a defective keyslot though,
or still some other problem with the passphrase entry. Especially
on updates non ISO-7bit (i.e. 7 bit ASCII) chars can cause problems.
In the cryptsetup source package, you find the keyslot-checker
in misc/keyslot_checker/. Install as described in the README and check
your keyslots for obvious problems. Next steps depend on the result.
