Since Debian 13 (Trixie), when using the default FDE which uses grub to decrypt the luks partition, I have a single attempt

When the password is mistyped there is a long pause (over 10 seconds) and then the error appears.

I already tried increasing the max tries, which seems to be set to 1 when a keyfile is used.

The config/script seems to be in /usr/share/initramfs-tools/scripts/local-top/cryptroot.

I copied that to /etc/initramfs-tools/scripts/local-top/cryptroot and replaced the value CRYPTTAB_OPTION_tries=1 with 10 using find/replace (ansible stuff).

I think this has no effect though and doing so (might be a different issue) breaks boot entirely 💀

More info:

  • by default when legacy boot (BIOS) is available, Debian will install grub to the MBR. This is where it happens
  • when forcing or prioritizing legacy boot and using GPT, debian somehow boots from a 300MB efi partition, the same happens though, one attempt

    Why install it from a package manager at that point? It’s probably more of a pain to get an Arch package working on Debian than it is to just build GRUB from source and install it according to whatever instructions GRUB distributes

      I meant the following:

      1. Find out the Debian package is too old
      2. Create Arch Live USB
      3. Boot Arch Live USB
      4. Copy GRUB config from the Debian install to the current Arch live system
      5. Install the up-to-date GRUB while in the Arch environment

      The bootloader installer package is distro dependent, the bootloader the package installs isn’t. You can boot Debian no matter if the GRUB is installed from Debian stable, Debian Sid, Arch, Fedora or even FreeBSD. Otherwise, dual booting wouldn’t work.

      Like I said, I’ve done that before, though with SystemD Boot instead of GRUB, which was a bit simpler due to how the bootloader is configured.
