Could still be an older initramfs image though. If you're able to reproduce this please run `cryptsetup --version` directly afterwards (i.e., at initramfs stage if that's where the issue appears). >> Looking at the upstream git log, I found >> 206b70c837f29c8b34cb0d80ae496870550ec50c >> which fixes https://gitlab.com/cryptsetup/cryptsetup/-/issues/488 which looks >> really familiar :-) > > It looks very similar.
