Thx. So, the keyslot 2 was not converted, but added later once device was already in luks2 mode.
Anyway, all offsets and parameters look correct, I was able to recreate the same sized device and it works for me (with upstream git, 2.0.2+). Can you try from command line for each slot and passphrases: cryptsetup luksOpen <device> --test-passphrase -T 1 -v If anything is not accepted (and you are sure the passphrase is correct:), please add --debug keyword and paste output here. Otherwise it is something special to Ubuntu that someone else have to analyse :-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755322 Title: logging in with luks2 converted encrypted disk only accepts keylsot #1 password To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1755322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
