Hello!
Reading some man pages, if you used the default encryption tool when installing
Debian you should be able to change the passphrase just with this:
cryptsetup luksChangeKey <your device>
If this isn't your case, we probably need some more details to be able to help
you.
Post by Richard BostromI cannot update my passphrase in crypttab
What did you try and what was the outcome?
Post by Richard Bostromalthough the passphrase is updated in the OS
How did you "update the passphrase in the OS"?
Post by Richard BostromI cannot enter my OS without using the latest passphrase.
What happens when you enter the old passphrase? And what when you enter the new
one?
P.S.: you should always choose a meaningful subject for your emails. "Security
Flaw" really looks spam and is easily discarded by spam filters, and even if
the message were delivered most people would probably throw it away without
even opening it. In your case there isn't a security flaw at all, so it is also
misleading. I'm just recommending to take care of your requests, people are
willing to help but don't have enough time to manually check every suspicious
message that reaches their inbox :).
