Hi I too encountered difficulty with trying to install the entire system (including /boot) on one encrypted partition.
The issue is this block of code: https://salsa.debian.org/installer-team/partman-crypto/-/blob/master/check.d/crypto_check_mountpoints#L94-102 This 17 year old "Check - Is there a /boot partition for encrypted root?" is no longer valid. Grub2 added support for accessing LUKS1 partitions in 2011 - https://git.savannah.gnu.org/cgit/grub.git/commit/?id=a251b71915e40194d12995dbac9efd787687f988 Grub2 support for LUK2 is also present but only for PBKDF2 keys - https://git.savannah.gnu.org/cgit/grub.git/commit/?id=365e0cc3e7e44151c14dd29514c2f870b49f9755 For people who use LUKS1 to do full disk encryption, this "Check - Is there a /boot partition for encrypted root?" is a blocker in the Debian installer. Dear maintainer(s), please review this bug report and remove this check. regards, Jinesh
